Support for mobile broadband provider database

[aa]

The NetworkManager project provides an  XML database containing carrier network details for a large number of countries. Support for parsing this database would greatly benefit the user experience when configuring a mobile broadband modem.

The database package is usually called mobile-broadband-provider-info.

The attached patch implements this feature atop the current work in #1622, so rebasing will be needed when those patches are r+.

Attached latest work, this applies to git HEAD. There are several visual modifications, so please let me know what you think.

Also new in this version is a config.py.in for generating config.py by autotools, and some minor nitpicks to shut pylint up :).

First of all, thanks for your work!

Sadly, as this is an enhancement and we are in Freeze already, I move it out to 0.90. If you (deployments) care strongly about it - please ask here for inclusion into a bugfix release 0.88.x.

Thanks!

Only trivial design niggles from me would be to right align the text labels next to the drop down menus, matching the rest of the existing fields; perhaps also make the drop down menus the same width as the existing input fields.
