google map sdk 3 support

[kibotu]

the google maps team apparently is working on v3

https://developers.google.com/maps/documentation/android-sdk/v3-client-migration

here are the examples: https://github.com/googlemaps/android-samples/tree/v3-beta

as far as i can tell the api didn't change, only the package name

would be cool if we had a branch for this :)
