- Added a idxstring parameter to ST_HasBasicIndex(). This allows ST_G…

…eoTableSummary() to search check if indexes with names containing strings like 'st_nbpoint' and 'st_area' already exists.

- Converted 'null' to 'NULL', 'true' to TRUE and 'false' to 'FALSE'.
- Make DISTINCT and GROUP BY on ST_AsEWKB(geom) instead of simply on geom which sometimes reports geometries as identical when they are not.
- Added 'NPOINTS' as an alias for 'VERTX' for the ST_GeoTableSummary() dosummary and skipsummary parameters.
- Fixed a logic problem preventing dosummary from being processed when only some skipsummary were invoked.
- Remove the last ST_Empty() test from the overlaps check in ST_GeoTableSummary(). It was preventing identical geometries overlaps to come out in the results.
- Changed the way we identify the outside polygon when listing gaps in ST_GeoTableSummary(). Now we check if the big external polygon ST_Intersects() with the exterior ring instead of just ignoring the first polygon dumped.
- SplitByGrid() now also returns the geometry representing the tile itself (tgeom).
