Fixed all messageboxes that can use struct object as self name
(e.g. m for messageboxes in mainwindow). Should help to avoid some
errors.
Added possibility to copy server's credentials into clipboard
for ease of sharing.
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.
Added checking if Urban Terror launched while trying to shut down
URTrator. If yes - we will show error message and won't quit,
until Urban Terror will be dead.
Now we have pooler which will pool connections (like pinging),
so there will be no timeouts due to "we have launched 100000 goroutines".
Reworked all code to use events (see Eventer). Still more work about
this to go.
Maybe more fixes I forgot.
Configuration is now properly saved for parameters in Options window.
Also they are restored fine.
Added tray icon with two default actions: show/hide and exit. More
to come.
