Several bug fixes;
Preliminar addition of the SDL 2 renderer (does not yet work correctly in full screen mode);

Removed all unused strings;
Removed some unused code files;
Significantly rewrote the bus mouse emulation.
Extensively cleaned up and changed the CD-ROM code;
Removed CD-ROM IOCTTL (it was causing performance and stability issues);
Turned a lot of things into device_t's;

Cleaned up the SCSI hard disk and Iomega ZIP code (but more cleanups of that are coming in the future);
In some occasions (IDE hard disks in multiple sector mode and SCSI hard disks) the status bar icon is no longer updated, should improve performance a bit;
