[Homematic IP] Add "Dump Configuration" Button

For hass “only” users it is complicated to dump a configuration to help us extend the homematicip rest api.
Therefore it would be nice to have some kind of “Dump Configuration” button on homeassistant which would basically run “hmip_cli.py --dump-configuration [–anonymize]”

i added a service to dump the configuration to the config directory.
anonymize is set to True by default.

That should be released with 0.102.

thanks =) I guess, that this will make it a lot easier for non developers.
