fixed a nullpointer exception when creating a new team

fixed the schemes on android

schemes/teams now get replaces on each version update

check if the widget is shown before checking if the finger is on the widget

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
