Fix Python 2 compatibility for the googlemaps module

Looks like that when the module was converted to be Python 3 compatible

Move the bundled pycha module to the bundle directory
Move the bundled configobj module to the bundle directory
Move the bundled geopy module to the bundle directory
Move the bundled upoints module to the bundle directory
Move the bundled googlemaps module to the bundle directory

Places API support.
