BS-4.7.0
Lint cleanup
Checked in the ZXing Test app for Android under androidtest. This application exercises all the intents we support including scanning, encoding, and searching books. It also has a special camera mode which saves greyscale images to the SD card which I use to generate blackbox images.
Additional changes for Android 4
Update ZXingTest to use Holo theme; requires Android 2.3.3
Update project site references to Github
