Title: Faster session date handling (partially solves #415)

The first commit, 065e33a3d13e4bfacd47d073f94206430d88f9ed, breaks the cookie format. Other than that, I feel it should be accepted.

The second commit, b2a9beba3cdd9e4df4f772af89fa991369e86013, is somewhat more controversial. We'll need a major version bump of yesod-core. It's also a bit complicated.
