Patch pebble's apk to support RTL languages

Currently I document the open issues here, if there'll be enough of them - we'll move to something more managed :)

• Sentences beginning with RTL text are wrong (should be resolved by passing the default orientation to the Bidi class and resolving the crashes that will arise)
• Line splitting by word separator (currently dumb)
• Line splitting by actual character width (currently dumb)
• Line splitting by font size (requires extra research)
• Try to align text to the right by padding with spaces

• RTL canned responsed (currently they're LTR)

Open the playground-app in Android Studio

• To improve RTL logic, change TextReverser class
• To improve the protocol parsing, change ModifierOutputStream

After changing the code:

• run "build-pg-app.sh"
• run "unpack-pg-app.sh"
• run "unpack-pebble-app.sh"
• run ./auto_patcher.py (defaults are good, but check out --help)
• run "generate-apk.sh"
• your home baked apk is at output-apks/bla.apk, not sorry for the name :)

The patch is supposed to be automatic, but it was never tested :)
In this version - the file to patch is: com/getpebble/android/b/c/e.smali
