This adds a special colorscheme and prompt function guaranteed to work on a VT and activates them automatically if $TERM = "linux". set_color is overridden to only allow the 8 colors VTs have (under the assumption those are always the same) and the color variables are shadowed with global ones so they don't pollute our nice capable terms.
