Alienating QSB

> Moving all QSB widget handling code in a separate package
> QSB is handled on a separate host, independent of the main
host. This allows us to safely reset either of the two hosts
> Also removing the logic around closeSystemDialog:
   Launcher does not use any panels which need closing
   System sends an onActivityResult(RESULT_CANCELLED), we do
   not need special handling for waitingForResult
> Fixing bug when auto-generated qsb widget id was not being saved
