Reorganize assets; switch the HUD to the Micro Chat font

Source packs move to assets/packs (untouched), maps to assets/maps, and the
palette/sketch leftovers from the 8-bit era go. tools/mkfont.py repacks
VEXED's Micro Chat sheet (8-column grid, 8x10 cells) into the CP437 atlas
layout the font loader already reads, cropped to 8x9 so the HUD can use an
8 px line height. The CGA atlas is dropped in its favor.
