Fix some warnings

Stop messages without possible desync on load from save

I didn't want to do this since it seems less clean, but... moving the stats-fix into CheckForWin, since that function is the one sending the damage stats (whyyyy?) therefore it's not sufficient to update stats after calling it, some of the stats won't be transfered to frontend then

Show who is the room admin on join (no tested, also I don't like how it is done via server warnings, but it seems there's no other solution compatible with .17)

skip second CheckForWin if water wasn't raised after first one

fix multi-shot related game ends leading to incomplete stats, fixes issue #372

More Qt-ish code, fix couple warnings.

Unset room restrictions on player/team joins when changing room admin

More precision

forgot to add back c96ff1a053d0

fix for issue #376 (embedding barrels in ceiling)

Fix line endings, add missing amMine entry

teleport hack fixes: * don't let hogs fall into other hogs, barrels or other gears * stop animation on damage (doesn't work with invul, sadly) * don't force waiting for ground-contact in inf attack mode * fix initially placing hog right next to instant-mine causing bugs

adjust velocity when entering/exiting the 4x routine

Let's try *4 instead. Not nearly as much of a win, but might be usable.
