Update build information:
- use maven-git-commit-id-plugin instead of maven-buildnumber-plugin (no installed git client required)
- update names from SVN to GIT
- add branch information
Merge pull request #71 from CarstenHollmann/feature/change_buildnumber_plugin

Update build information
Add maven-release-plugin generated files to ignore
- Add samplingGeometry column to observation mapping files.
- Add updatescript to create samplingGeometry column to observation table and update values from spatialfilteringprofile table.
Mark as deprecated because it is no longer required after moving samplingGeometry to observation table
Update SpatialFilteringProfile description because this setting is deprecated after moving samplingGeometry
- Add methods to:
  - insert/query samplingGeometry column from observation table
  - filter for samplingGeometry column
  - create OmObservations from entities with samplingGeometry column
- Check if old or new SpatialFilteringProfile handling is supported to use the corresponding methods
Update Hibernate mapping files:
- use unique-key instead of unique to avoid unique constraint name generation which can cause problems when updating the database model.
Add schema update strategy for unique constraints. Use RECREATE_QUIETLY instead of default DROP_RECREATE_QUIETLY which cause problems when the SOS tries to remove the old constraints and they do not exist.
Update used DatabaseMetadata constructor. Old constructor is deprecated.
SQL scripts to drop the previously generated unique constraint names.
Reuse the code to identify the database exceptions if the identifier or the observationIdentity (series, phentime, resulttime) already exists in the database.
This was commented out because in the previously used Hibernate version the unique-key definition from the mapping files were ignored.
