Cc/admin additional fields

# Changes to the Wordpress Administrator Page

## Field Entry Modifications
Added additional fields to support configuring this plugin for Web Service.  The new fields include a space to enter web service username, and the web service license key.  This information is generally supplied by the vendor - https://www.maxmind.com/en/home. 

All of the variables are still saved in the options location for Wordpress.

## Service Selector Option 
Added a service selector drop down to the admin page, so that administrators can toggle between local DB service and Web Service.
