Change the lock-in system to a ready style system

Locking in your selected champion has worked fine for a while now, however with missions requiring you to have a team of a specific comp/champion, and for what could be a better experience overall for normal/ranked games, having a ready based confirmation system instead of the lock-in style for champ select could be an improvement.

It could work similar too, where you need to confirm "ready" for all 5(3) team members in order to skip the champion select timer. However, confirming ready does not mean locking in. It just allows the team to skip the timer. Players could unready to swap champions if desired or needed too (draft modes will not be changed much from the current way though). Especially in the special game modes where most of the comp/champion specific missions revolve around.
