Brought CGA code in line with mainline as the patch was accepted.

Browse Source 
Uncommented auto-setting FDC data rate to 250 kbps on non-AT machines; fixes floppies on IBM PC and XT and clones;
Removed flto flag from the makefiles, should speed up compile times and make the XT and earlier machines work again;
Removed CGA brown and color burst settings in line with mainline PCem.
