C++ Constant-Q

Expose overlap and decimator option

Merge

Merge from branch chroma-in-library

Pull out chroma class into library

Feature labels were upside down in the plugin! Oops. Fix it

Various changes to make the code compatible with MSVC++ (though we don't provide projects for it yet)

Another fix to parameter defaults

Correct order of min/max

Avoid failing if min and max frequency are identical

Update RDF, copyright dates etc

Expose some more processing parameters, use a single parameter class

More necessary code, some work on build scripts

Smaller range, faster chromagram

Make CQVamp implement two plugins, one with MIDI pitch range and one with Hz

Inverse runs; now merely needs to run correctly

Interpolation for CQ. But this is wrong, it is interpolating between points in the nearest full-height columns even where there is a nearer point in the not-full-height ones

Put spectrogram the "right" way up, add bin labels

Use MIDI pitch values, as in QM Vamp Plugins implementation

Get remaining blocks from end of processing; fix some compile warnings, etc
