Removing handlers and replacing Jurassic

Jurassic was throwing a stackoverflow exception in debug mode so I
replaced it.

With the removal of the handlers caching is now performed by static
content cache instructions set in the web.config.

This incorporates the resource clearing fixes from fixes and pull #21
Stop that sql nag
Fixes issue #12

Contents are moved as per scope grouping but scripts are no longer
broken as a result.
