Buildbotapi

Nothing fancy to show in the PR, but a lot of infra to allow the real UI to show up including:

- some codeStyle fixes
- move to bootstrap 3
- move to restangular, including changes needed for updating scope on SSEs
- more unit tests.
- dataspec.js is generated from the data spec available in the python code, this allow to help a lot in CS unit tests and
- backendless development framework, for playing with the UI without having to generate data with buildbot.
