This fixes horrible ^CS ^CR bug, sometimes fail.

Color Save, Color Restored (sometimes broken)!

Symptom was missing Main Menu top line.
It was in wordplay mangle.  When we divide
the buffer into text/ansi, we were using the
"main" console.  Which we would play the
buffer into *AGAIN* later on.

We now use a copy of console (to split things
up), and play the buffer just once into the
console.  We now NAIL the color everytime!

I process_trigger@render.cpp:666 restore color [4/0/1]

Before this would vary, depending on what was in
the buffer.  It should always be the same because
Mystic prompt and input is always the same color,
which is the last color before CLRSCR.
