New --pattern option

Hello all,

Just a heads up that I made a change (in svn trunk - not yet released)
that may change what files get loaded when you run the rake or spec
commands. Not a big deal if you’ve been following convention, but for
those who haven’t you may need to make a minor adjustment to your rake
file or spec.opts.
