Trying out some cache settings.  The goal being to get Javascript
source files to cache.  Right now they are verified that they are
not modified.  Hopefully we can get it to completely eliminate this
verification step for performance reasons.
Commented out some meta tags that are not being honored in the default.jsp
template.

Added more caching comments in the Spring config regard the resource
servlet.

Added the catalina.jar dependency to Maven because Tomcat has the ability
to use the ExpiresFilter to control caching parameters in headers.
The web.xml contains the settings for it.
