RMGreatCircleAnnotation bug - and fix

[zivlevy]

RMGreatCircleAnnotation has a bug that it displays the great circle with out its beginning.
To correct you need to add this line at RMGreatCircleAnnotation.m:70
[coords addObject:[[CLLocation alloc] initWithLatitude:self.coordinate1.latitude longitude:self.coordinate1.longitude]];
