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.
