[WIP] Adding latest markup to aid in requireJS optimizer configuration

- [x] Remove all unused flat-ui and twitter bootstrap assets
- [x] Add in latest markup for login, navigation etc.
- [ ] Fix content loading as it currently breaks the new breadcrumb component

As part of issue #16, we need to trim all of the fat that was left over from the twitter boostrap/flat-ui approach we initially started with.

This PR removes all of that, and brings in the latest content from the tickit-templates repository as a basis.

After this PR has been completed merged, it will allow us to concentrate of #16.
