Update crash dialog options.

Add app info to crash dialog. Show close (aka force stop) on all dialogs,
not just the repeat dialog.

Remove showing restart and mute by default. Add Settings.Global
configuration parameters for both in case we want to show those options again.

Also some minor cleanup (converting some members to locals).
