DOSBox SVN

Add opl3gold option to oplmode setting. With this option the AdLib Gold music can be selected in Dune. Only FM music without effects (reverb, stereo enhancement, surround sound, etc.) is supported; and FM volume control, used in the CD-ROM version of Dune, does work.

VS2015 wants it this way

More robust parsing, so that dosbox -fullscreen A.EXE works

Slight reordering of the arguments. Add -socket

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.

Only compile when in debug mode.

Display a simple startup message for sub-shells instead of the welcome banner.

Add some more cases to the Alt-tab detection. It can still mess up, but this should help with a lot of cases. Thanks for testing eightbitbubsy.

Slight compression, so that we have more space at the bottom for height restricted screens.
Add some colours to the prompt, so it is more visible.
General improvements to the section parsing

Fix shell PAUSE command when reading extended keys, and make TYPE command more compatible by stopping at EOF byte.
