Title: Hook instead of RC_FILES; Increased verbosity.

Pry::RC_FILES went away recently, in this commit:
https://github.com/pry/pry/commit/d830ebbacc6ebaf60261855ef6011bd6b9d47d8d

The hooks should work both in 0.9.10 and HEAD pry.

Also, gave the user a hint about ~/.guardrc, because it changes the
interactor experience quite a bit with/without one.
