Ironruby core - Jan 2008 - [patch] downto/upto

Hey,

In the process of running one of my script on IronRuby I needed upto,
so here it is, along with his downto friend.

I was wondering if I could simply call Step with the relevant limit
and step from upto/downto, but wasn''t sure that was correct.

I''ve basically monkey saw, monkey did the whole thing, please correct
me if I got some parts wrong.

Looks good. I think you''re right about Step though. I''ll try
replacing the methods with direct calls to Step and see if it works.
