Chrss update 2

Updates to chrss:

  • now setting guid for moves in the rss feed (so the entries can be told apart, even though they point to the same url)
  • when you sign up you should no longer get redirected back to the sign up page after you first log in
  • if you create an account, when accepting an invite, you should get redirected back to the original join link when you log in (uses a cookie to record the "join url")
  • added info about whose move is next when browsing games
