Fixed the BIOS files used by the AMSTRAD PC1512, fixes #366;
Ported the Unicode CD image file name fix from VARCem, fixes #365;
Fixed high density floppy disks on the Xi8088, fixes #359;
Fixed some bugs in the Hercules emulation, fixes #346, fixes #358;
Fixed the SCSI hard disk mode sense pages, fixes #356;
Removed the AMI Unknown 386SX because of impossibility to identify the chipset, closes #349;
Fixed bugs in the serial mouse emulation, fixes #344;
Compiled 86Box binaries now include all the required .DLL's, fixes #341;
