Champion Search Functionality

@Riot

Just a small suggestion for Champion Select.

During the ban phase for certain game modes (Poro King, for example) I generally have a decent idea for what I actually want to ban, and what I actually want to play.

It would, simply, be very nice to be able to type something like 'nid+gal+sora' into the search bar to have Nidalee, Galio, and Soraka all show up. Or 'nid, gal, sora' Or both!

Or something along those lines.

Opine, masses?
