PeaksAndValleys needs equal billing with TunnelTilt

[pelegri]

The first paragraph of the README file mentions that TunnelTilt can be run on the browser but does not mention PeaksAndValleys until several paragraphs below.

The first paragraph should mention PeaksAndValleys. And, ideally, there should be a staged version of the game (via gh-pages)

Will take a look this week. I'll need some local Github guru here to help me with the gh-pages setup but shouldn't be a huge hurdle.
