Minimum viable Android M runtime permissions handling for H.

Creates new activity for permissions handling: both checking
for permissions and handling error condition when critical
permissions are not present. The reason for creating a
new activity is so the app does not attempt to continue
executing OnCreate, OnResume etc, which opens
the camera while the dialogs are showing. This should
not slow the app down because the permissions activity
will only run when a) the first time the app has
insufficient permissions and b) when a critical
permission is missing and the app needs to shut down.

Fixes to M permissions.

Previously, we called PermissionsActivity with startActivityForResult().
However, this creates race conditions as we check for permissions
and the CameraActivity continues to operate. Now, we end CameraActivity
and launch a new instance upon successful permissions resolution.
We can also put the preload filmstrip logic back in its original
place in onCreate. The checks for permissions happen in both
onCreate and onResume.
