By using a QToolBox, we can better utilize the available space for
long lists of DLCs. `GameDlcWidget` is now responsible for handling
installing and uninstalling the DLC based on RareGame's functionality.
Since `GameUtils` is not used for uninstalling any more, remove it the
arguments of `GameInfoTabs` completely.
Since pyuic5 doesn't handle `connectSlotByName=False` in ui files
use sed in `misc/ui2py.sh` to remove those lines
