Add the REM interface generators (tools) and ignore dumps, logs and server files

make_icon_3db, make_image_3db and make_hud_txm with their helpers, standalone
(the name CRC table is in flcrc.py). The .gitignore keeps crash dumps, logs,
traces, debug symbols and everything of the server out of the mod.

+"""A coloured Freelancer interface image (.3db) from a PNG -- for pictures in the REM windows
+(statistics medals, banners, portraits), shown with a StaticControl like the inventory's item
+icons. Unlike make_icon_3db.py the colours stay and the quad keeps the picture's aspect.

+    python tools/make_image_3db.py <in.png> <out.3db> <name> [--size 256] [--nocrop] [--crop x0,y0,x1,y1]
+
+The transparent border is cut off (unless --nocrop), the picture is stretched into a square
+texture of --size pixels (three mips) and drawn on a quad of the picture's aspect, the longer
+side as long as the retail icon quad. --crop cuts that pixel rectangle out first (a banner
+strip from a square picture). <name> gives the material "UI_REMIMG_<name>", the texture
+"REMIMG_<name>.tga" and the mesh library "rem_img_<name>.lod0.vms".
