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.

Basic workarounds for overlapping drawn map (rename buttons) and short team list (set a min height). Min size of form still fits targetted min size on desktop of 800x600

Add shoppamap lua as mikade requested. also add 50% chance of bottom border w/ holes as he requested. Also disable land objects in shoppa scheme, since that's more common way to play it.

I don't see how rating these against others is useful, given the limited radius, and the cluster bomb thing just seems counterproductive. Anyway, this prevents AI from picking on barrels.
