* Collection: fix match testing for attributes.
* Fix a NULL pointer dereference when deregistering an event listener that
doesn't include a detail.
* Fix the documentation for interfaces in collection match rules.
* Add an AtspiLive enum to specify the politeness level for live regions,

the politeness information.
