User bower for js packages
Included jquery-ui in bower.json
Updated event name of bootstrap-tokenfield
Fixed autocomplete for tags

I removed the autocomplete js ui module and
only import the jquery-ui.min.js and that
somehow fixed the autocomplete in bootstrap-
tokenfield.

Also the functional test had to be updated to use
new selectors for autocomplete testing.
Moved qunit-tests into a view with a template

This means, we can use normal staticfiles app to
serve the files instead of hardcoding paths.
travis has to install the bower-stuff, too...
Moved bower install to before_script part of travis.yml
