- 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.
