GESTimelineFileSource: Add 'max-duration' and 'supported-formats' properties

Browse source 
* max-duration is the total length of the File.
* supported-formats is the various track types this filesource can produce
  trackobjects for. This should maybe be moved to parent classes in the
  future

Step 1 of GstDiscoverer integration
