i have re-mapped strafeleft/-right, not left/right
no translucency, no translucent HUD
R_InitTranMap() now properly prints a mark during init phase

The mark reflects its status:
: TRANMAP loaded from a lump
. TRANMAP loaded from tranmap.dat file
! TRANMAP generated and saved to tranmap.dat file
? TRANMAP generated, but not saved
fix parentheses in m_menu.c
apply plums' solution to fix translucent blues
plums is happiest with this patch, so be it

fixes #39
