[Mapstraction] [mapstraction] r58 committed - V1 geocoder with minor changes to work with V2--structural changes sti...

As an initial test, I switched the LatLonPoint calls in the previous  
geocoder to use mxn.LatLonPoint. It worked with Mapstraction V2.  
There''s still a lot of old Mapstraction code to remove from the  
geocoder. It still has switch.. case statements and is otherwise set  
up The Old Way. What I have committed is workable, but not ideal.

Rob--I''d still love an example of a barebones plugin. Without it I  
can''t be sure if the failure to lazy load is due to issues with the  
loader or issues on my end.
