This removes various code paths that we believe to be unused.
* The userguides miner has been removed altogether.
* The application miner no longer parses MeeGo-style .desktop files
* The TRACKER_DISABLE_MEEGOTOUCH_LOCALE environment flag is gone
(it already did nothing)
* Character set detection with libmeegotouch is removed, only enca
or libicu are supported
* Meego-specific flags are gone from .desktop files
* Functional tests have lost their vestigal Scratchbox and Aegis support
There are 5 ontologies referencing Maemo, 4 of which are largely unused.
