Log Message:
-----------
new UI rna function
layout.prop_search_self(), the same as layout.prop_search() except it uses an attribute of the collection.

A number of collections have an 'active' member which couldnt be used with prop_search() and meant we had a mix of active properties being in collections and directly added as properties.
