Make ^L with cons25 and origin mode bit more sane.

Browse Source 
Even though cons25 normally doesn't support origin regions, this
emulator does allow you to do it. It makes more sense to blank only the
origin region when emitting ^L instead of blanking the entire screen.
Apart from that, we should always place the cursor inside the origin
region, which doesn't happen right now.
