Quit cider popup buffers with 'append argument

  The default behavior of `quite-window` is to remove the buffer from the
  selected window's buffer history. We want to use the 'append action instead of
  'bury to preserve the buffer in the history to allow future invocations of
  `display-buffer` and `pop-to-buffer` to reuse the window.

[Fix #867] Fix (cider-grimoire-lookup) regression due to HTTP 301 (Moved Permanently) to the old Grimoire URL.

Grimoire recently migrates to "http://conj.io". The old URL used in
(cider-grimoire-lookup) would drop the "Content-Type: text/plain"
request enroute of a HTTP 301 redirection.

Updating the Grimoire URL to "http://conj.io" fixes the issue.
