Fixed a tiny bug in the Cirrus Logic blitter;
Adding DEV_BRANCH=y parameter to make now compiles the Cirrus Logic emulation code *and* the Nvidia Riva emulation code;
The Sierra SC1502x RAMDAC emulation code is now correctly named as such;
The makefile now knows the dependencies for a lot more files (with the unfortunate effect that 86Box.exe is now 8 MB after stripping);
win_setting.c no longer includes scsi_buslogic.c - that was a leftover of long gone code.
