mARsquerade Non-cardboard mode added

I have added a monocular branch to the mARsquerade project in github. It allows the app to be used without Google Cardboard i.e. like a camera app. There is take picture button which saves images to /sdcard/Pictures/mARsquerade but it doesn’t save the masks on top of the photos yet and there is no gallery built into the app. I’ve got these features on my to do list. When the app first starts it asks if you want to use Cardboard or not. The monocular mode can only be used in landscape for now.
