Promote Media Markers.cs

/*

  This script will "promote" the markers and regions embedded in the
  selected events' media to project markers and regions.

  Note that more than one marker can not exist in the same
  location. When this type of failure occurs, the script records the
  error, contiues promoting the remainder of the markers and regions,
  and informs you of which ones failed upon completion.

  This script is only supported by Vegas version 6.0c and above.
