Fixed mapicon, changed appicon, changed issue url

- fixed the mapicon bug, where it doesn't show up on the device. Looks like Device is case sensitive and Simulator not.

- changed the appicon option, so it doesn't add the glossy on it. The new [site](http://new.onebusaway.org/) is without glare.

- changed the bug tracker url to the github repo instead of google code. It was a dead link.
