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).

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.

/*
* SCSP_Init(n):

* Parameters:
* n Number of SCSPs to create. Always use 2!

* Returns:
* FAIL if an error occured (prints own error messages), OKAY otherwise.

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 :/
