feat(*): included AngularUI `utils` to use uiRoute

uiRoute has replaced the `activeIfCurrent` directive. To support it,
`angular-ui-utils` has been added as a Bower dependency. However, since
it is not a built version, only the uiRoute was added to the build.

Closes #13.
Merge pull request #30 from joshdmiller/merge013
