[JC-1936] - Proof of concet about the sotucion regarding html scaping
treated in the UI, using the spring:message tag with htmlScape set to
true.

The .js involced that are commited are the developer versions. If it is
decided to apply this solution, it would be better to include the
minified versions of both files. (jquery-1.11.1.min.js and
jquery-migrate-1.2.1.min.js).
