Fast black screen shutdown and remove LCD splash

[sastraxi]

• remove the built-in splash now that lcd-splash takes care of it for us
• remove has_system_splash (always True now)
• ensure that subprocesses get joined quickly so that they don't block shutdown
• add a dismissable arg, True by default, to message dialogs
• uses non-dismissable modal dialogs for terminal states (Shutting down..., Rebooting..., Restarting Sound Engine...)

I think I kindof preferred the screen transitions (restart sound engine, shutdown) without the black screen, but this if fine too. And yeah, good to get rid of the old splash.

That’s fair—maybe a better approach would be to put up a standard “Please wait…” modal rather than blacking out.
