Proper migration to pelican 3.2

When I moved over to my new computer, I had also changed the version of pelican that I use to generate this blog. Superficially everything seemed to work, but then I discovered that a few things were broken. So today I sat down and migrated properly and in this process cleaned up a bit.

One thing that went away is my half-baked commenting system, which while working, failed to attract a single comments in the three years of its existence. I already have plans to replace it with something better.
