NetDuke32: General to-do

Stuff I need to fix:

• Some useractors, like robot mice can noclip outside of the map. Old behavior from DOS Duke, but a very bad one.
• Duke Talk from certain triggers do not play from the activating player like they should. (World Tour maps are good example)
• The return to center functions, and look up/down keys do not perfectly re-center the view.
• The DEF token loadgrp fails to work from a GRP/PK3.
• Crouched player sprite sinks into the floor.
• Spawning too many sprites (in excess of 10,000) causes an overflow/memory corruption in online play. This one is serious. (Fixed, I think.)
• The vertical mouselook inexplicably forces itself to center at random, or if the framerate suffers enough.
• Monster kills in CO-OP aren't credited to the one doing the killing, but the nearest player to the monster.
• Underwater mines are able to get knocked around by explosions. (Need to verify if this is vanilla behaviour first.)
• The end of level screen in SP has seizure-inducing flickers. Need to clear the screen before drawing.
• Color codes aren't stripped from the title bar.
• CON parser complains about "predicting" var being used in local states. There are valid uses for it, so I must suppress this warning.
• Friendly fire mode doesn't clear completely when switching to free-for-all. Blood sprites fail to spawn especially.
• Respawns break in co-op if there's only one spawn point.
• For whatever reason, netduke32_settings.cfg keeps resetting.
• Breaking ceiling lights produces no sound, need to see why.

Stuff that needs implementation:

• The ability to add, remove, and block teams.
• Soundfont selection in sound menu.
• Quitting matches should return to the main menu/logo sequence, not outright terminate.
• FOV Slider. (Implemented only as console command, for now.)
• CO-OP Scoreboard & Intermission Screen
• Show player name in screenpeek mode.
