Add a warning when you get a group invite which will make you quit your LFG queue.
Description
It's purpose is to avoid leaving your LFG queue by accepting an invite and cliking too fast the accept button.
It will add a second warning so you really know that you're leaving your queue.
Please note that it won't work if you have an auto-accept addon enabled...
