Voting process overview should be foldable

[davecgh]

The voting process overview at the top should probably be hidden by default with a way to unfold it for details. Once you have read it and understand the process, there is no longer a need to see it on every visit to the site.

The status is the most important information one would want to see after familiarizing themselves with the process.
