Webservice Configuration

Allows the plugin to be configured via admin settings page for either local db or webservice

We started using this plugin about 3 days ago and really like it but for the sake of our users we felt it was timely to add this configuration for the maxmind webservice.

This adds a selection to switch between `webservice` and `localdb`
And the fields associated with the webservice namely `user_id` and `license_key`

Thanks for this plugin.
