need those default color.

for me, it is nice to allow pepole to cancel the tool. without this
option, how can you allow people to quit once they dont want to run
anymore? so i think it is fine to keep it that way.

by the way, pygrub is an ugly name. the fact that this tool is written
in python is what users care least. how about renamming it to a more
make-sense name? like xengrub, or (even better) xenloader?
