Show message and return from network game pages on server shutdown

- Register HWTeam metatype so HWTeam objects could be passed via queued connections - A bit more verbose server message about unknown protocol command

Make all signals from HWNet queued, this should fix issues with teams and chat widgets

added one button play feature, like in desktop frontend; need to make sure that the hardcoded stuff never gets deleted

ipad, have the scheme/weapon/style selector always stick in the same position

missions page rotates correctly

two more this time
