Title: Make Scala2 derive from prog-mode

Since scala2 is a programming language mode, it'd make sense for it to automatically call `prog-mode-hook` after loading, so that a user can do things like run specific minor modes only in programming modes.

It seems like `define-derived-mode` is the way the emacs docs suggest to do this. If there's a more common approach, that'd be better.
