use container-fluid for the toolbar

With class container buttons will disappear to a not visible area
when resizing the interface smaller (smartphones).
In OERPUB we also use more buttons than atc
and exceeding the bootstrap container size of 940px.
Make sure nested editables (ie notes) are not big
Replaced link onclick with explicit calls to controller to update

Bonus: you can click on a bigger area to begin editing from the ToC
tree or the search results list
Merge branch 'master' in
Added Saveable Model

Just checking hasChanged or isNew is not enough. hasChanged is cleared
after every set.
