Integration with tracker

[diego]

There could be three ways to integrate with tracker:
  a) Making referencer use tracker as backend
  b) Adding the metadata to files already indexed by tracker
  c) Provide a tracker extension that allows it to integrate the information in referencer files

This is not a bug, it is a request for enhancement. It would be very useful if referencer would include this information. I think the most useful way to integrate would be 2.
