Bug 9964

Fixes bug where context_key is always set to 'web' on new resources created by "Import Resources" or "Import HTML". Now checks the context_key of the parent resource the user specifies. 

Also added a comment regarding the "import_context" value - that doesn't seem to be an option in the input form anywhere. (And the concept doesn't really make sense when a parent resource is already being specified, because children will always be in the same context as the parent, right?). I think this block is obsolete and can be removed(?)
