[mythtv] lcd contents when shutting down frontend

[Arthur van Dongen]

Hi all,

When mythfrontend is closed normally, the menu contents remain on the
LCD. This makes it harder to switch off the frontend when the TV is
already off. I see a few enhancements to make this easier for the users:

1. mythfrontend: copy exit dialog to LCD so user can see what's being
selected
2. mythlcdserver: clear all ouput texts from mythfontend
3. mythwelcome: add interface to mythlcdserver to show recording &
shutdown status

I'm willing to attempt to work on this. Any ideas?
And should I enter a trac issue for this? Combined or separate?
