Fixes for iOS 7
	Set tint colour for search and navigation bars so buttons appear white in iOS 7 (not default blue)
	Included uses of R2RSearchButton to give buttons a background and border for iOS 7. Primarily for the buttons floating over images/maps.
	Added UIStatusBarStyleLightContent for controllers without a navigation bar to set it automatically.
	Adjusted position of r2r status button for iOS 7 to compensate for the phones top status bar.
	Used [self.mapView deselectAnnotation:self.pressAnnotation animated:YES] when setting locations to prevent iOS 7 crashes from trying to remove the annotation twice.
	Set [self.mapView setDelegate:nil] in viewDidUnload to prevent crashes when delegate is called after map is destroyed (this may need to be in returnToSearch).
	Fixed header height for walkDrive segments.
