[TIMOB-17688] iOS8: Add ability to request Geo Location Permission

With iOS8 now there is the need to request specific geo location permissions. The PR for this method is here https://github.com/appcelerator/titanium_mobile/pull/6073 How to test this can be found here https://gist.github.com/benbahrenburg/4bcda636397cb095025f The API for this is pretty simple

Ti.Geolocation.requestAuthorization(Ti.Geolocation.AUTHORIZATION_ALWAYS);

Ti.Geolocation.requestAuthorization(Ti.Geolocation.AUTHORIZATION_WHEN_IN_USE);

[~cng] Make sure to remove the merge-3.4.0 label and add the "Release 3.4.0" fix version (in the future).

Seeing a problem with this when the app is backgrounded: 1. App starts, dialog pops up asking "Allow myapp to access your location while you use the app?" (Don't Allow/Allow) 2. Click screen lock or wait until it locks 3. Unlock the screen 4. The geolocation authorization dialog is gone, geolocation events don't fire Any ideas how to deal with this? Thanks

The above comment applies to iOS 8 simulator and device. iOS 7 simulator works fine - the dialog is there after screen unlock.

Update: this appears to be horrendous new behavior under iOS 8...... The Google Maps app also doesn't show the permission dialog after a screen lock.
