Title: MapControl local Mv store RTree

On the map editor component. Keep a local copy of row's geometry envelope in a rtree cached on disk (mvstore).
Rendering of smaller portion of map is now faster thanks to this local rtree. This optimisation work with local H2 database and remote PostGIS database.It doesn't require a primary key or spatial index on the table.
