added option to set videoMirrored to AVCaptureConnection

new mirror button to turn video mirroring on/off
Observe exposure changes in addition to focus changes

Exposure can be changed when using the front facing camera
Listen to exposure changes PBJViewController

Always show the ‘_focusButton’ and when exposure finished changing,
stop animating the ‘_focusView’. This has a direct effect when using
the front facing camera.
