Upgraded jetty to 8.1.14.  Fixed some syntax errors in jsp files

I don't know if this is something you will want to have in master or not, but this pull request upgrades Jetty to version 8.1.14, and brings the servlet api up to 3.0 along with it.  We were having some garbage collection issues locally and this helped a bit.  Going to the most recent 7.x version of Jetty would have a similar effect without requiring java 6.
