Various SCSP improvements and code cleanup: - Ported MAME's implementation - Corrected FM sound for songs in VF3 that use it - Music tempo now closer to real hardware thanks to emulating two SCSP chips. - Add LegacySoundDSP config option for games with SCSP DSP glitches (ex. engine noises in Sega Rally 2, and loud garbage on Bahn's stage in Fighting Vipers 2) - Renamed SysFPS to "SoundClock" (since raising this appears to adjust the sound frequency).

Getting rid of most of the includes from Supermodel.h; each file now explicitly includes the header files it needs. Making changes to a header file should no longer force the entire project to recompile.

First part of SCSP clean up: pointer arithmetic made more safe (I hope). To-do: convert data types to Supermodel standards.

- Improved 68K interface. Now supports context switching. - CSoundBoard is not derived from CBus. - Optimized sound board memory handlers (now using switch statements). - Added DSB emulation (based on R. Belmont's M1 source code). - Improved ROM loading: only unique ROMs (those not shared amongst games) are used to identify games. The ROM loader will no longer get confused as easily. - General cleanup here and there, removed unused Render.h file.

* Returns:

Massive internal change: removed CConfig object and replaced it with a hierarchical config object system (Util::Config::Node). Games are now defined in an XML file. Hopefully I didn't break too many things :/

change all INT16 mixing/intermediate clamping to floats also fixes 3 bugs: 1) mpeg right channel volume was always using the left channel volume, too 2) too high MusicVolume setting was not clamped to 0..200 3) too high SoundVolume setting was not clamped to 0..200
