v1.2.0

Added configuration options for which metadata to import and for units.

Added support for following built in metadata fields: location, city, state/provence, country.
Added following custom metadata fields: dive site name, dive identifier
Support for fields varies with the import format as not all formats publish every field.

Metadata import has been streamlined further and is now done more programmatically which should reduce risk of errors and makes it easier to add additional fields.
