Renamed some stuff in SectionArrayAdapter
Cosmetic refactor. Moved code around in SectionCursorAdapter.
Renamed some methods so that they match in both section adapters. Add some missing methods to SectionCursorAdapter
SectionArrayAdapter should always be able to handle data nulls now.
Fixed a bug with lists starting with null sections.
