Subject: Add the missing bits for the new region-search: - Added lookup in the
 data-layer   - MySQL works   - SQLite doesn't have a grid-db, so it won't
 work there   - I added MSSQL-code to the best of my knowledge; but I don't
 know MSSQL :-) - Added the plumbing up to OGS1GridServices. This speaks with
 the grid-server   via XMLRPC. - Modified MapSearchModule to use the new data.
 It's backward compatible; if   used with an old grid-server, it just returns
 one found region instead of a   list. - Refactored a bit. Note: This updates
 data, grid-server and region code. No new files.
