Facebook and Twitter integration

As part of an ongoing change, I've just released a new version of panoye. You'll probably notice a few minor layout changes, but the biggest one is in the "comments" section:

In short:

1. The list of comments is now more concise and readable,
2. With the Twitter and Facebook widgets where you can share panoramas you like/upload with your friends.

Feel free to contact me if there is any problem with the new version.
