Sage prompt in color

It is possible to activate colors for sage prompts in the terminal which is done by editing the file

$HOME/.sage/ipython/ipythonrc

As said by W. Stein on sage-devel :

"It has numerous color options, which are off by default since it is not possible to tell if the user's terminal has a white or black background, and any choice of colors looks like crap if you guess wrong about the background color."

# keep uncommented only the one you want:
#colors Linux
colors LightBG
#colors NoColor
