Webscripts (or plain javascript) in the repo tier can now optionally provide an additional 'store' reference as the first argument to the various search APIs:

- search.luceneSearch("TEXT:alfresco") <- original API
 - search.luceneSearch("workspace://SiteStore", "TEXT:website") <- new API
This allows script developers to search other stores such as the new SiteStore.

NOTE: some script writers were trying to use the public Sping bean setter method on the Search object called setStoreUrl() as a hack to do this previously - that technique is NOT thread safe and should not be used - that mechanism has now been blocked by the bean and will throw an exception.
