Default Android text

Instead of nothing, we now default to "Loading" for the Android message.

2.0.0

• Rewrite in TypeScript
• Support for more options of MBProgressHUD and ProgressDialog
• Demo app for development and trying out
• A more object-oriented approach, by creating LoadingIndicator instances

Big thanks to @NathanWalker for this work on this release.
