Minor reordering and refactoring of the web.xml fragment to make sure the DTD is valid once its included
For the moment just ignore the sass plugin in the eclipse lifecycle
Changed the execution of the sass plugin to build on incremental so changes to sass get noticed by eclipse.  Also, in order to get eclipse to understand that the output of the sass plugin in part of the project I had to change the output location and then add it back in as a resource.
Merge branch 'master' of github.com:ucam-cl-dtg/urop-2013-frontend
