[aprssig] Google maps live

[Steve Dimse]

OK, based on the feedback, I have switched the primary maps over to  
Google. I still have some work to go to get the options for the  
different maps updated (making APRSworld maps an option). The program  
roughly checks for a position in North America, and uses the map  
feature as the default, otherwise it uses the satellite maps as the  
default.

Let me know if anyone has problems other than those related to the  
security settings of IE6...
