Show a message if a background plugin is not starred

Summary:
Since background plugins don't receive data anymore when not starred, we should hint the user about this.

For this diff, I reused the existing statusbar. Although this solution is quite ugly, I think it is better than introducing yet another notification / warning mechanism. Probably we should revisit the layout of this status bar in the future.
