1- create a sub-directory called bootstrap under the image webapp to put
the resources over there (js, css and fonts) as indicated earlier by Gavin.
(Julien : not sure about location)
2- check to make sure that the current version of jQuery is compatible with
the installed version or upgrade it accordingly
3- Create a new theme based on one of the existing themes as suggested by
Julien and Gavin
