Debug web UI support for Throw notify

Duk_debug.js fixes for Throw notify

- Ignore unknown Notify messages, this is probably a better default than
  being strict and dropping the connection.

- Add Throw notify command number (earlier GC notify was unused).

- Add minimal web UI integration to report "THROW: xxx" or "UNCAUGHT: xxx"
  from Throw notifys

Add 'make rundebug' convenience duk_debug target with logging.
