change default timestamp format to hh:mm

automated the build process some more, users must add the android ndk, sdk and fpc dir to their $PATH and cmake will do the rest, I still need a solution for the sdl dir. Subrepo's perhaps?

* fix highlighting (i just broke it by not negating a boolean expression) * fix issues with first display: none; being ignored + allow css to hide hours / seconds of timestamp

added lines to avoid compiler hints, is this really the way we want to do it though? ;/

update name autocompletion after nick change (since own nick isn't suggested)

merge

disconnect when going back from lobby page (regression fix) fix some indentations
