'p' is now a binding to the levelup interface, no more silly shift+letter

Introducing a new evolution path for high level characters: Prodigies. They are a bunch of talents tied to having high stat (>= 50) and some other requirement. They are only one level, you may learn one at 40 and one at 50. They can do anything and are *not* class bound.
