screen_manager: If a running process exits, a resulting action should be run.

[coderkevin]

Right now, if an action is run, and it exits (either normally or not), the user is left to look at the console with no recourse. This isn't the best situation.

Proposal ideas are:

• Hard code to run the default action after the process exits
• Add another section to the config that is run after the action process exits

I've got a workaround, at least as far as returning to Emulation Station is concerned. I have a runcommand-onend script write the dashboard command to the cfg file after an emulator exits.
