Subject: [PATCH] Copy elementId in Clay__AddHashMapItem() in case underlying
 stringId has moved

If the string reference passed to an element id has changed between frames (e.g. moved), then the reference stored in the hash item can become stale. This change makes sure that we're always using the latest value.
