Subject: [PATCH] Add a release script.

Summary: Make the release script that's been floating around in my gists
for a while into a real script.

Test Plan:
 - Comment out all the scary bits (the two pushes, and `npm
   publish`), and run:
 - `./release.sh 0.6.0`
 - Checkout the `v0.6.0` tag, see that it successfully modified
   package.json and bower.json to version 0.6.0, and built and committed
   the rest of the files.
 - `git tag -d v0.6.0`
 - `./release.sh 0.6.0 0.7.0`
 - Checkout master, see that it successfully made a commit bumping
   package.json and bower.json to 0.7.0-pre.
