Invite System ReVamped

something I notice with a lot of team builder games and normals where a group is coming up with roles and want a 4th or 5th. is getting a 5th, then leaving because the role that is left.

solution: add a feature to the UI where players may check roles they desire to be invited for (may check 1-4 or check fill for any). and then in the invite list of friends and chat rooms, you may filter by role.

(i.e. jungle main account only plays jungle, he would check jungle, so he would show up in the jungle list in the invite screen and be invited to be a jungler)

Thoughts?
