Merged floppy.c and fdd.c and renamed floppy_*.c (the floppy image format handlers) to fdd_*.c; Reading the AT or PS/2 keyboard controller status no longer clears the transmit timeout bit, fixes error 8601 (mouse error) on the IBM PS/2 Model 80; MMU translate and DMA physical reads and writes now go through _mem_exec instead of directly to ram[], should fix the last remaining problems with remapped mappings; Implemented the Sound gain dialog; Added the resource for the "New floppy image" dialog and the needed functions for the functionality of exporting the currently mounted floppy image as 86F, both of which should be finished in the next commit; Applied the CD-ROM fixes from the PCem commit; Added the "Keep ratio" option for full screen stretch.
