As I'm the only code contributor, I'm announcing that URTrator code
is now licensed under MIT license.
Also I'm deprecating Qt5 interface as it is really hard to write Qt
code and create installers with it. Maybe one day I even figure out
how to work with QtQuick (which attracts me more and more ATM) and
URTrator will use it, but not now.
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.
