Support Konsole

[l0b0]

"In Konsole it shows 0 whereas actually it supports 256 colors..."

Using MacOS X's terminal also yields 0.
Tried locally and after ssh'ing into a Debian box.

EDIT: I wonder if there is anywhere to find the correct control sequence for those other terminals. Of if they even exist. We could test color 1 to see which one is valid and make a universal script.
