Right now, if someone does not have Spectre configured correctly, they can create content and try to commit it.  The commit fails and they end up being frustrated and writing nasty grams on TBB and the discussion forum.  Worse, they might just leave in a huff and not use wG anymore.

I would like to propose that we give them some feedback when they try to commit if WebGUI cannot talk to Spectre.

1. Refactor out the spectre connection code from Operation::Spectre::www_spectreStatus so that it can be used by other modules.
2. Add a spectre check to
   1. VersionTag::RequestCommit
   2. Operation::VersionTag::www_commitVersionTag
   3. A new macro that people can add to their pages that, when the user is Admin, will tell them if Spectre is up and running.
