Apparently alternate screen is evil - Add config to disable it

[sjurba]

Apparently, lots of people find the alternate screen to be evil. I have no problem with it but since some do, I figured we might as well add a switch to disable it.

You might argue that you shouldn't need to configure the app specifically for this, that I should respect some global term config and figure it out on my own. But, ain't got time for that shit. But maybe terminal-kit does, so if you want that fixed, take it up with him. I think that titeInhibit will work, what ever that means.

But a simple switch to disable it from my app, that I can do:
--no-alternate-screen
