Rename submersible state, increase getaway time for attack underwater, slow down gear dx/dy underwater to simulate water resistance

Actually, let's use *4 since could be fired from lower down

more drowning fixes

check for gear being current ammo

yeah. this needs to only be for local play or it screws up small window size in network game

some saucer thing for firing weps underwater and aiming and such. bit drunk and sleepy so testing I guess

fix issue #590, load nick after asking for it...

range checking for more engine command line parameters, issue #600

fix comparison error in Campaign mission 1

Restore ready toggle for room admins (issue #432)

Needs to reset net button, not toggle it.

use less collision space for the holes

don't draw a border if there's already a bottom border, avoid placing objects over gaps in the floor

Package the 3 dynamic maps broken by recent uFloat changes as static maps. first_blood actually didn't seem to need it, but, just in case.

suggestion of unc0rr's to fix issue w/ random maps in campaign. load sidecar packages in physfs for lua. should be useful also for lua that does custom layouts
