DeSelect All Conferences

  Be very careful of this option.  By using this function all conferences
  will be DeSelected for Scanning.  This can beneficial in some cases
  where a user wants to get rid of a bunch of conferences from reading.

  This function is very FAST and takes only a second to wipe out
  everything.  Be sure you're doing the right thing as there's no way
  to fix it once you've answered Yes to the prompt.
