Fixed a bug in blank_degrees.module, where future draft catalog years couldn't be selected for
  viewing.  Also changed wording on admin.module's form, which sets the draft catalog year, to make
  it clear that it only affects the Blank Degree Search feature, not What If.

  Made various changes to some of the core code, in preparation of a new module, "audit", which
  required extra calculations for quality points.  Also, made slight changes to the core comments
  module, so it can accomodate more access_types (again, will be used by the upcoming "audit" module).

  Fixed bug with "ghost hours" in _DatabaseHandler.php.  When a course has zero hours for
  either min or max hours, it was changing into 1 hours when duplicated to a new catalog year.

  Made minor documenation changes to various functions.
