feat(coffee): CoffeeScript support

CoffeeScript files are now supported out of the box. Any coffeescript
files in `src/` that match `*.coffee` will be linted and included in
the tests and builds.

Just to demo that it works, the `titleService` has been migrated to
CoffeeScript.
fix(*): ui.route from bower is out of date

v0.0.3 is not yet available in Bower but v0.0.2 does not support
ui-router. This commit switches temporarily to a static version of
ui.route.
