o Remove NFCDemo sample app. It's janky and is mostly parsing code
that isn't needed anymore.
o Use new NDEF APIs for parsing and creating records
o Use nicer setNdefPushMessage() API
o Delete helper NDEF code that is not needed any more
o Use URL instead of Text for the foreground push demo
o Mark AndroidBeamDemo a test so it gets installed in data not system
