77bb9df6a6 Reset CurMode object when detecting that the video mode number in BIOS memory was modified directly instead of through the INT 10h mode set function. Fixes cases where BIOS behavior is influenced with the mode number, such as the status line in Bruce Lee. 
Set color modes (to the extent that they can be) on the Hercules machine type if the BIOS equipment list is not set to monochrome. Fixes missing text in Victory Road.

1b7b92ed8a Add alternate font tables and associated loading logic in video BIOS, allowing correct gaps between "wide" characters (e.g. m,w,M,W,T,Z,0) in all VGA machine types. 
Update all related BIOS memory values and CRTC registers when loading fonts, fixing quirks in some textmode programs like Inertia Player. Based in part on a patch by h-a-l-9000.

Improve support for MDA emulation in the vgaonly machine type, as it is the only way the video BIOS can make use of the 14-line alternate symbols.

Be compatible by setting the INT 43h vector to the first half of the 8-line font table for standard text modes. Fixes a few obscure games and demos that rely on this BIOS behavior.

Move VESA mode table and OEM string before font tables in the video ROM, which is a more compatible ordering and gives the data low address offsets that work around a bug in some programs such as the Abuse game and Molejo demo.
