Feature 3g database support

Provides and easy to use mechanism of entering the configuration settings for 3G modems. The user can select 'Country', 'Plan' and 'Provider' from drop down boxes, and the required settings for the modem will automatically be configured. For some modems which require specific user names or passwords, the user can still manually input those settings.

Thus this is an add-on to existing functionality, where all settings must be manually typed in into the text-entry fields.
