rakep 'watch' option

[bobspryn]

I would love to have a rakep watch option, where it just watches for updated files and builds updated files. This would eliminate the need to use the :9292 port when addressing the files during development. This would make it easier to use in lots of different environments, for instance alongside different backends like GAE that run on their own ports in development.

I was interested in a rakep watch option as well, so I added one on my fork: https://github.com/melindaweathers/rake-pipeline (on the "watcher" branch). Feedback welcome. I haven't submitted a pull request just yet. You can access it with just "bundle exec rakep watch".

#64 addresses this.

@twinturbo does #99 address this?

@wagenet ya you can close this. This behavior is unneeded now.
