Fixes bug 908410 - Made supersearch UI use the SuperSearch service [DO NOT MERGE]

Please note that this is not ready yet. However, it is close enough to what it will be in the end that I can open a pull request and ask for review. 

What needs to be done:
- [x] Add an admin mode that will allow users to see ``email``, ``url``... 
- [ ] Fix links to the ``report/list`` page (bug [https://bugzilla.mozilla.org/show_bug.cgi?id=897139](897139))
- [x] Improve the design (results are quite ugly at the moment)
- [x] Fix a few small bugs, test the whole thing more
