Avoid rare double decrement.

Prevent pirate ship from repeating on Islands, remove vertical line in art landback

bug #370

Oh, should also check for game finish when player quits without ROUNDFINISHED message: small refactoring, not tested at all

comment out reserve to maintain old Qt compat

Also consider game finished when the last player reports ROUNDFINISHED despite the correctness parameter.

Someone might find this useful. Plan to link to it from the wiki.

Fix for bug #366, delete gear if hog is drowning (needed either that or a check on nil Gear^.Hedgehog^.Gear)

Don't remove client's teams from teams list on "ROUNDFINISHED 0", just send team removal message to others. This should fix problems with ghost teams in frontend. Not tested at all, successfully built on first attempt, which is considered as a bad sign :D Server still thinks game proceeds, so restart isn't possible.

oops
