ENH: Add private/public view studies

Private and public studies are now listed when you go to Study>{Private/Public}
the interface was built using DataTables which makes searching and browsing
through the available data very simple, provides an easy-to-use querying
functionality.

I've added Bootstrap's glyphicons to the repo as they were not there before.
Note that I didn't have to modify the license for this addtion but for the
addition of Bootstrap.

The study description is there as a place-holder as @antgonza indicated he
would work on that.
