Better support recaching in restful filters and handlers

[GoogleCodeExporter]

Ups, that wasn't my latest version.
I think its the easiest way to always set the instVar if caching is disabled.

routes
"Answer a collection of routes for the receiver."
^self shouldCacheRoutes
ifFalse: [ routes := self createRoutes ]
ifTrue: [  routes ifNil: [ routes := self createRoutes ] ]

Make sure any patches are applied both to WARestfulHandler and WARestfulFilter
