Removing language comparisons

[A.M. Kuchling]

python.org has a page of "Python vs. X" language comparisons at
<http://www.python.org/doc/Comparisons.html>.  They're all pretty outdated,
and often unfair because they're written by a person who knows Python well
but has only a nodding acquaintance with language X.  

I'm planning to drop this page from python.org because it's so outdated and
no one is around to maintain it.  If anyone wants to grab the contents and
turn them into a Wiki page, or use bits of them for marketing material,
please do it now.
