[Pydotorg-redesign] Redesigned version of current home page

[A.M. Kuchling]

After some c.l.python discussion, here's a revised version of some 
tweaks to the current home page.  The sidebar has had a few more links 
added and subtracted, and the top bar has had the number of links 
trimmed from 8 to 6, making the list short enough that it can be put 
into a single row.

Comments?  Can I begin implementing these changes on python.org?
