Library for ansi color management.

Having now experienced the unbelievable difference it makes to
have one's voluminous debugging output effectively color-coded,
I had to librarize the ansi codes in order to use them.  This
could all go in the standard library, or as soon as I can easily
make use of compiler dependencies, a separate library altogether.
For now it hides away in scala.tools.util.color.
