In this cycle we did a lot of finetuning on the gtk+3 port. More deprecated APIs
are replaced with the new API. We did a lot of work on theming; e.g. all colors
are now defined in the css files and settings let you select theme variants such
as a dark theme.
The interaction controller library now supports alsa-sequencer. The UI for
training the controls of a new midi device is streamlined and much easier. Also
the controls from the interaction controller can be used fro playback controls
Finally things got easier for developers too. We merged bml, gst-buzztrax into
buzztrax to simplify the build.
