Reduced sound gain options to one (because the per-source gain does not work right);
Added the Diamond SpeedStar PRO (CL-GD 5428), per patch from TheCollector1995.
Added internal graphics card option for the Intel Advanced/EV for the on-board S3 Trio64;
Fixed configuration for internal graphics card options (using the machine's Configure button) for some machines (PCjr, Tandy 1000, Tandy 1000 HX, and now also the Intel Advanced/EV).
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.
Applied all the video-related PCem commits;
The keyboard ALT+TAB detection now sends one extra ALT key down and up, so the guest does not get stuck in a menu bar.
Removed the Mach64 ISA until someone finds a properly working BIOS;
Changed the Mach64 VLB to use the BIOS that actually works;
Moved the standalone TI CF62011 graphics card to the Dev branch until someone finds a BIOS for it;
Removed an accidental temporary change in win_dialog.c;
Reorganized the graphics card ID's to allow simplification of the MDA and VGA #define's in video.h;
Added a workaround for the TVGA8900D DAC sense, so the card is in color again.
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.
Applied all applicable PCem commits;
The PS/1 and PS/2 machines now have the correct graphics cards - fixes the reference diskettes;
The open dialog code now changes directory to usr_path after the dialog is closed;
Disabled excess logging in the TI SVGA code.
Re-worked the system pathnames (pc.c), renamed cfg_path to usr_path.
Other small things here and there.
Logitech bus mouse re-worked, should be OK now.
Bugfixes in config.c regarding CD-ROM defaults and IDE channel reading;
Applied all the PCem Voodoo commits;
The Sound Blaster cards' OPL can now be disabled for slight performance gain.
