Initial version of Carla plugin for LMMS

Initial version of Carla for LMMS.

There are 2 plugins - Carla Patchbay and Carla Rack.
The InstrumentViews don't have any artwork, and this should be considered a work in progress.

I have some questions regarding the LMMS Instrument API but I'll leave those for the mailing list.
