Added a width limitation in the same way it is done on the UploadPresentationRenederer.mxml.

Added the Truncate attribute to the label, labels too long to be displayed will now be truncated and appended wit "...".
The full name of the file will be displayed as tooltip on mouseOver for all the downloadable files in the Download Window.
