Fix an error where the geolocate dialog wasn't loading properly

For some reason, a standard tweet dialog was being used to display this information, which comes along with spell check, translate, etc; functions a simple geolocate display box doesn't need.
The error was happening because the tweet show dialog was accepting (tweet, tweetList, is_tweet=True) as args, and the call to display the geodata was only providing geodata as tweet, and false as tweetList.
This method signature was erroring out because is_tweet was set to True by default; the False was being accepted as tweetList, which the method later tries to call __str__ which it doesn't have.
I could have just added the is_tweet keyword, but then I would need to change the signature so tweetList is set to none by default, update the method, bla, bla, bla. Too much work.
Instead I added another function in wxUI.commonMessageDialogs called view_geodata, which just accepts the data in question as an argument and displays that in a message box.
