[IMPROVED] Type of Master Password counter is unsigned int; Guava's
UnsignedInteger allows us to better enforce that in code,
fixing a few places where ints were treated badly, limiting
counter support.
[ADDED] An integrity test activity to the Android app to ensure the
Android device properly generates the expected passwords
before allowing the user to rely on it.
[UPDATED] Made standard test suite available for all without needing
JAXB; implemented SAX reading of mpw_tests.xml + a good API
for running the tests and getting feedback at runtime.
[FIXED] A Java UTF-8 encoding issue.
[FIXED] Android 4.4 wasn't triggering onClick on TextViews.
[ADDED] A notification when the password is copied.
[ADDED] Expire the password from the clipboard after 20 seconds.
[UPDATED] -underscore variant of slf4j-android to make tags settable with setprops
[UPDATED] Opal API
[ADDED] Scrypt native binaries for more archs.
[IMPROVED] Android activity secure.
[FIXED] White background on buttons for some devices.
