Issue #156: Camera.DestinationType.FILE_URI on Android not conforming to API Spec

Instead of capturing the orginal image to /sdcard/Pic.jpg or /sdcard/Capture.jpg we detect if the SD card is mounted. If mounted the file is placed in the apps temp directory at:

/sdcard/Android/data/{package name}/cache/

If the SD card is not mounted we default to internal storage at:

/data/data/{package name}/cache/
