Removed excess memset()'s from hdd_image.c and did a few other optimizations there, also fixed incorrect zero'ing of the buffer in hdd_image_write_ex();

Did a tweak to mmutranslate() in mem.c, should increase performance again;
Added the ATi VGA Wonder and ATi VGA-88, made the ATi VGA Edge-16 use the correct BIOS.
