clients can be disabled (the default)
- fix teleporter space checking to only check the space a player would
take up
- add a check so that teslas can't get negative health when hacking.
(shouldn't happen?!)
- clean up building placement, so that anywhere from 20 below to 30
above your feet is fair game. it then checks for solid a second
time if the top was solid
- add defines for checkmove (SV_Move wrapper)'s type field
(MOVE_NORMAL, MOVE_NOMONSTER, MOVE_MISSILE)
- add a printtrace function, since I do it so often in debugging.
- BUGS, TODO
