Now everything that uses Profiles from cache will also use it's
mutex to lock access. This brings more stability improvements :).
Also fixed profile update in database.
Qt5 interface is now translated (kinda).
Fixed a bunch of data races which should lead in stability improvements.
Added possibility to specify game profile path within profile item.
Added Urban Terror 4.3.2.
Refactored the way URTrator working with profiles - now everything
that could be taken from internal cache will be taken from cache.
The very same as with servers.
Moved all callbacks from callbacks to events, so we achieve full
asynchronity here and can launch anything in goroutines :).
Moved MainWindow-related game launching functions into another
file (mainwindow_launch.go).
Made quick connect widget working. Note, that even if you're on
Favorites and trying to connect to one of favorited servers but
with quick connect - you still have to choose right profile
near Launch button!
Maybe something else I forget.
