Enable use of Google maps libraries

[patrik-enqvist]

I'd like to be able to use google maps additional libs (https://developers.google.com/maps/documentation/javascript/libraries) such as:

• geometry
• places

Suggestions for solution:

• Use an extended option for giving the libraries to load and then append them to the url used to load google maps

...aaaaand I found the options already in place... closing this.
