This change consolidates more unit handling and conversion into
QgsUnitTypes.
Additionally, UnknownUnit was renamed to UnknownDistanceUnit.
All methods which accepted QGis::UnitType parameters have been
updated to take QgsUnitTypes::DistanceUnit instead.
ALso remove the unit handling methods toLiteral, fromLiteral, tr,
fromTr, and fromUnitToUnitFactor from QGis. Their corresponding
counterparts in QgsUnitTypes should be used instead.
- update methods of existing classes
- add comment to methods missing in the sip bindings
- split up collective sip files into single files and use
same directory structure in python/ as in src/
- add a lot of missing classes (some might not make sense because of
missing python methods in those classes)
- remove some non-existing methods from the header files
- add scripts/sipdiff
- replace some usages of std::vector and std::set with QVector/QSet
- more API cleanups
- single click (instead of drag) to select a feature (fixes#1154)
- fixes for topological editing
