Implementation stubs for various WMS 1.3 handlers. Started implementation on GetCapabilities + renderer.
Improved mapserver layer connector interface and implementations. Now the coverage and data items are directly passed instead of the ominous 'data_statements'. Extended the layer factory index with the 'suffix' attribute. Inserted the layer factory extension point to the mapserver component.
Moved some of the responsibilities (DB lookups) to the handler. Various cleanups and improvements.
Cleaned up renderer and adjusted to new interface. Now properly calls the 'disconnect' method of the connector.
Log exception traceback to debug stream.
