CD-ROM images are now working correctly again;

Fixed all the reported bugs regarding the Settings dialog;
MIDI out device is now no longer reset to 0 after hard reset;
Removed all vestiges of the old disk activity flash;
The configuration file is no longer saved when it shouldn't be;
Redone the status bar icon updating so it is only done in win.c;
Made sure all variables in ibm.h are extern;
A lot of other bugfixes;
Added Mouse Systems Mouse emulation (patch from TheCollector1995);
Added IBM PS/1 Model 2133 (486) emulation (patch from TheCollector1995);
Tweaked the CPU dynamic recompiler cycle periods - 486SX 33 and 486DX 33 now work;
Increased compatibility with configuration files from before the previous commit.
