Inital implementation of the device properties API.

Added new interfaces to qmpMidiOutDevice.
Implemented the new interfaces for qmpMidiOutFluid.
Initial infra for device initialization file parsing.
Move to the new interfaces for getting list of presets.
Use DevIL instead of CxImage.

External output devices are broken now but that is for
another commit.
