Hard code the terminal codes.

Browse source 
May as well hard code them since only supporting gnome-terminal and
stterm atm.
Only one code differed between stterm & gnome-terminal,
"terminal.normal", and have taken the gnome-terminal version for now.
stterm seems to work fine with gnome-terminal's version.
