Merge from default branch

-Changes in Sonic Visualiser 2.5 since the previous release 2.4.1:
+
+Changes in Sonic Visualiser 3.2 since the previous release 3.1.1:
+
+ - Add feature to convert and import audio from a CSV data file
+
+
+Changes in Sonic Visualiser 3.1.1 (Aug 2018) since the previous release 3.1:
+
+ - Fix failure to record correctly into an empty session with certain
+   audio drivers
+
+ - Fix failure to run LADSPA plugins at all, except with some unusual
+   path layouts
+
+ - Fix failure to silence sonified notes when rewinding backwards or
+   jumping back from a loop endpoint
+
+ - Fix macOS .dmg image so as to use older HFS+ filesystem for compatibility
+
+
+Changes in Sonic Visualiser 3.1 (July 2018) since the previous release 3.0.3:
+
+ - Add Plugins tab to Preferences dialog, from which you can review
+   the plugin load paths and see which plugins were loaded from which
+   locations, and also customise load paths (though the various path
+   environment variables are still supported)
+
+ - Stream the export of audio data and other CSV data so that
+   very large exports don't hang the UI or run us out of memory
+   (thanks to Lucas Thompson)
+
+ - Ensure vertical scale appears for auto-align layers when there is
+   nothing else to auto-align them to
+
+ - Fix another long-standing Windows-platform wide-char/utf8
+   conversion problem, with environment variable naming and contents
+
+ - Improve handling of incomplete session loads, i.e. situations where
+   the audio files referred to by a session could not be found -
+   previously the session could be re-saved immediately thus losing
+   the audio reference; now at least we disable Save (enabling only
+   Save As) and show a warning
+
+ - Update pane and layer menu shortcuts so that the
+   waveform/spectrogram/etc shortcuts (Shift+G etc) operate on the
+   source model in the currently-selected pane rather than the main
+   model. This is a backward-incompatible change but is a far more
+   intuitive way for the function to work
+
+ - Use dark background for bright colours in time-value/note/etc
+   layers as well as e.g. waveforms - this is how it was always
+   "intended to" work, but it is a backward-incompatible change
+
+ - Make "Select All" select the whole span of everything that exists,
+   not just the main model
+
+ - Add horizontal scale to Spectrum layer
+
+ - Improve spacing and labelling of vertical log scales
+
+ - Update build system for better Cap'n Proto version support and to
+   use Repoint for code management in the repository
+
+ - Various other bug fixes
+
+
+Changes in Sonic Visualiser 3.0.3 (May 2017) since the previous release 3.0.2:
+
+ - Improve decisions about where and how to label vertical scales
+
+ - Update build support material and documentation to reflect the
+   official release of Cap'n Proto 0.6 (which we can now use rather
+   than depending on git builds)
+
+
+Changes in Sonic Visualiser 3.0.2 (Mar 2017) since the previous release 3.0.1:
+
+ - Fix crash when changing parameters for spectrum view
+
+ - Fix incorrect measure tool crosshairs in spectrum view
+
+ - Update Russian and Czech UI translations (thanks to Alexandre Prokoudine
+   and Pavel Fric respectively)
+
+
+Changes in Sonic Visualiser 3.0.1 (Mar 2017) since the previous release 3.0:
+
+ - Fix crashes with MIDI devices and speedup/slowdown control on Windows
+
+ - Update MIDI input driver layer
+
+
+Changes in Sonic Visualiser 3.0 (Mar 2017) since the previous release 2.5:
+
+ - Add ability to record audio, and ability to change the audio device
+   for playback or recording in the preferences
+
+ - Add complete support for high-resolution (Hi-DPI or retina)
+   displays, including for layer data rendering as well as UI controls
+   and icons. This makes the biggest difference when using a retina
+   Mac, on which previous versions did not render layer data at retina
+   resolution, but it also improves scaling and rendering of UI
+   elements on Hi-DPI displays on Windows and Linux
+
+ - Add ability to export scalable (SVG) image files
+
+ - Run plugins in a separate process, so that if a plugin crashes, it
+   no longer brings down Sonic Visualiser with it. In every other
+   respect the behaviour should be unchanged
+
+ - Scan plugins on startup in a separate process, and report on any
+   that crash or won't load
+
+ - Add ability to open, display, and analyse very long audio files (of
+   more than 2^32 sample frames)
+
+ - Change mp3 file loading so as to compensate for encoder/decoder
+   delay and padding (using "gapless playback" logic). While this is a
+   real improvement, unfortunately it does mean that the initial
+   padding in mp3 file load has changed from previous versions, which
+   may mean some sessions saved in previous versions are no longer
+   correctly aligned. It's not a great idea to use mp3 as a file
+   format of record, because of differences like this between
+   decoders. The previous behaviour is still available as a preference.
+
+ - Add new Hybrid normalisation type for spectrogram and colour 3d
+   plot layers. This normalises each column to its peak value and then
+   scales the normalised values by the log of the peak in order to
+   restore some distinction in scale between columns with different
+   levels. It can provide quite visually clear results.
+
+ - Add function to subdivide time instant layers into regular
+   intervals (and its inverse)
+
+ - Add new preference for default colour scales
+
+ - Add a basic ability to zoom (in the frequency axis) to the spectrum
+
+ - Switch to using combined level/pan controls in layer property boxes
+   and for the main volume control
+
+ - Make CSV file reader better able to handle files with varying
+   numbers of columns
+
+ - Fix a number of problems on Windows with loading and saving some
+   file formats to filenames not representable in system codepage
+
+ - Add "What's New" dialog
+
+ - Finally switch the Windows build to 64-bit by default (with
+   adapters to run either 32- or 64-bit plugins)
+
+
+Changes in Sonic Visualiser 2.5 (Oct 2015) since the previous release 2.4.1:
 
  - Add unit-converter dialog, for converting between various pitch and
    timing units
 
  - Fix failure to reload note layers from session file

    gesture (where available)

  - You can now insert time instants, time values, and notes using
  a MIDI device during playback.  If a time value or note layer is

  loaded at the same time.  This option is enabled when the MATCH Vamp
  plugin is installed.  When alignment is switched on and more than one
  audio file is open, SV will assume that all open files are
