Radar view map zoom controls on iOS

[evanblack]

Currently, the zoom controls for the google map when you're in radar view don't show up on iOS. This may be because iOS uses gesture support for zooming and such. May need to look into the maps api to see if there's a config option.

By default, iOS disables the zoom controls because gestures are typically used with the maps api. Setting the 'draggable' map option to false prevents gestures though. The ideal solution is to re-enable the draggable option and grab the new map center on the bounds changed event to pass that lat and long into the radar image api. However, there is a flaw because of the disconnect between the Google Maps zoom level and the Weather Underground radar image zoom level.

The current solution is to keep the 'draggable' option disabled and to force the zoom controls to the device.
