googlemaps plugin uses geometry functions to compute lat, long

[titaniumbones]

the googlemaps plugin relies in several places on the google.maps.geometry API. The geometry library is no longer loaded by default (docs here). It should be possible to manage without it, since we are not for the most part doing any complex math here.

I don't know enough about the API yet to have a solution, but it would make sense to investigate this as part of #68.
