Update map command (see PR notes!)

[h-anjru]

The utilities/map command required an update because both the MapQuest API and the Bitly API had ceased to function; neither are free for use any longer. The command is updated to use the TomTom API, which has a handsome daily allowance of free usage.

The TomTom API more easily allows the user to specify a zoom level, so this functionality has been passed on to the user. From >help map:

>map <location>

Get a map of a location using its name.
You can also specify a zoom level 1-22.
1 is zoomed out the most; 10 is the default.

Example usage: >map hell; 14

This will require that config.py be updated, as we have switched from MapQuest to TomTom API. References to MAPQUEST_API_KEY are now to TOMTOM_API_KEY.
