[Suggestion] Streamline champ select by remembering choices

Currently, the client remembers your skin selection for each champion. Why not also have it remember your rune page, mastery page, and summoner spell selections? That would help avoid the situation where a player ends up running out of time before making their selections after changing their selected champion to fit their team's needs, don't you think?

The coders might have to be careful with how mastery pages all slide down 1 spot when an earlier page gets deleted, but it should be easy to deal with that if it's kept in mind during implementation.
