Configuration and maintenance interface for openHAB

You can persist *Item* states. This is useful for charts
and to restore *Item* states on startup for example.

## Additional Items

You can specifiy specific items to persist.
Additionally you can define a filter pattern and
every item that matches that filter will be persisted as well.

The filter term is a regex expression.

A common filter is ".*" which means: All items.
