Very basic camera capability - needs more work
Keep screen on during preview for 30 secs, rotate preview, few fixes
Added default flash, jpeg quality, image size and white balance
parameters.
think I fixed call_state_idle reception
move camera button next to torch button
we require 4.3, so we shouldn’t need to set a deprecated setting from <3.0
simplify camera stuff and fix layout
don’t let screen turn off while camera is initializing
Fixed issue with app widget display - tidied refreshDisplay
Added metadata to images so display at end of gallery, trimmed preview
to more of a square shape, switched to a better focus mode
fix orientation tracking during camera preview
Merge branch 'camera2' (close #19)

- don’t crash gallery by saving with orientation>360
