Add globals build and bower build script

@rwjblue I think this covers the build steps we discussed:

* remove `globalize` export
* introduce globals build
* introduce bower build script

Please review the bower build script carefully, since I have yet to run it. You may also want to add your own email and user name instead of Tomster's ;)

Once merged, we still need to tweak travis.yml to run the build script with the right credentials.
