add color to botany 

Add example ANSI-colored ASCII art to "art" directory

Add ansi_render() to menu_screen.py to render ANSI-colored ASCII art

Fall back on non-colored art if no colored art exists

Only single escape codes for setting foreground color are supported.
Escape sequences with multiple codes (e.g. "ESC[1;33m") are unsupported.
Unsupported escape codes reset colors to normal.
