MOB-29: Content Storage Lifecycle Management

- Some collapsing of common code in Constraint hierarchy.
 - Added aspect 'cm:storeSelector' with property 'cm:storeName'.
 - Defined a new, unused content store 'storeSelectorContentStore' (see content-services-context.xml).
   If this store is used, then setting the 'cm:storeName' property will force content to be stored in one
   of the named stores.  A LIST constraint is indirectly enforced for the 'cm:storeName' property.
