Add Popeye to the list of packages.

Looks good to me! I can confirm that:

• the links on the home page look good
• the new Popeye page itself, and it's links, are good
• addition of Popeye to the sidebar.
• Popeye is in the snakey thoughts

If others want to take a look:

Thanks!

One minor detail—no capitalization on the 'p' :]
