API: Added support for bulk loading of spatial index

This is much faster way of initializing a spatial index. From python it is as simple as
>>> index = QgsSpatialIndex( layer.getFeatures() )

From a simple test with 50K points in a memory layer:
- bulk loading ~ 100 ms
- inserting features ~ 600 ms

The index tree should be in theory also better constructed and may result in faster lookups.
