* Avoid failing on second and subsequent input files in single-output-file
  mode (because first input file caused output file to be open, so second
  input file failed because output "already existed")

Changes in Sonic Annotator 0.4 since the previous release 0.3:

Build changes:

 - Sonic Annotator now requires the Vamp plugin SDK v2.1 or newer.

Front-end changes:

 - Frequency-domain plugins now use the PluginInputDomainAdapter's new
 ShiftData processing method, ensuring that the first block received
 by the plugin is the one centred on 0 rather than starting at 0.
 Unfortunately, the old behaviour omitted a timing compensation step,
 and this fix actually changes the results from some plugin processes:
 the previous behaviour was not always in line with the Vamp plugin
 specification.

 - More useful diagnostics are now available when a plugin fails to
 load or run.

CSV back-end (feature writer) changes:

 - The CSV writer now closes its output files properly when it
 finishes writing to each one, rather than leaving them all open
 until the end and risk running out of file descriptors.  This was
 already the behaviour of the RDF writer, the CSV one has just been
 updated to match it.
 - The behaviour of the CSV writer has also been changed to match
 that of the RDF writer in handling file write failures (it now
 continues processing only if --force is given).


Changes in Sonic Annotator 0.3 since the previous release 0.2:

Front-end changes:

 - A new --force front-end option (distinct from the --csv-force and
 --rdf-force back-end options) has been added, which makes Sonic
 Annotator continue to process subsequent audio files instead of
 exiting after an error, if multiple audio files have been specified.

RDF back-end (feature writer) changes:

 - The RDF writer now conforms more correctly with the Music Ontology
 in the way it relates signal, track, and track metadata.  Signals
 that have available metadata now gain a Track resource to associate
 that metadata with, instead of hanging it directly from the Signal
 resource; also the audio file now encodes the signal rather than the
 signal being available as the audio file (matching the domain
 specification of the Music Ontology).  Note that this new resource
 structure will not be properly read by versions of Sonic Visualiser
 prior to 1.6 (should importing the data into Sonic Visualiser be of
 interest to you).

 - The --rdf-signal-uri option has been removed and replaced with the
 more meaningful set of options --rdf-audiofile-uri, --rdf-track-uri,
 and --rdf-maker-uri.

 - A new --rdf-network option is available, to cause Sonic Annotator
 to try to retrieve RDF descriptions for plugins from the network
 where those descriptions are not available locally.  Use of this
 option is recommended, but it is not the default because of the
 possible performance implication (even though the results are mostly
 cached, there may be some network access involved).

 - The RDF writer now writes the computed_by property for signal
 features.

 - Plugin and output URIs in the resulting RDF are now percent-encoded.
