The main bulk of this is the new start screen code. To make this work in Raze some more work on the startup procedure is needed.
What this does provide is support for the DOS end-of-game text screens in Duke and SW on non-Windows systems.
Mainly this means that it's no longer necessary to reorder the palette to get working translated glyphs, so the FFontChar1 class and the TranslatedPic member and its invasive handling could all be cleaned out.
All font operations now take place on true color data, with the sole execption of FSpecialFont's 'notranslate' handling.
The base palette can be set via .def files so that the engine has no access to it until the entire game state is set up.
This means that font translations and PNG palette remap tables cannot be built when the owning objects are created.
For PNGs this has the added advantage that they only get done when really required and not unconditionally - most of the time the remap table isn't even needed here.
Thid fixes the slider graphics in the option menus.

This pulls in a lot of Doom specific font setup, this can be sorted out later as it won't get into the way.
