sip coverage fixes:

* make sip coverage test aware that there are less classes where QSci sip
  headers are not available
* exclude properties from members
* fix QgsFeatureIds typedef (fixes missing signal
  QgsVectorLayer.featuresDeleted and others)
* add missing notes for PyNames
* include some missing new methods in bindings
