remove requirement for Googlemaps API key

[hvorragend]

the information may not be required for simple use of the module and the popup warnings are major annoying.

This is only true if the googlemaps JS api v3 is used I think. The v2 requires the api key to be used with the terms.
But the new Javascript api does not require it any more, so it can be removed if the code is using the new api.

Content is already using the new v3 JS api and that makes the maps look more modern again :-)
