* Total overhaul of V_DrawFadeScreen(color, strength!

- controllable strengths between 0-31 for COLORMAP lump like before
   - arbitrary colour indices in the palette via TRANSMAP lumps, with strengths 0-9
   - exposed to Lua as v.fadeScreen(color, strength)!
* Remove last vestiges of V_STATICPATCH.
