#37: Add timestamp type to BB interfaces
---------------------+------------------------------------------------------
 Reporter:  tim      |       Owner:  tim       
     Type:  feature  |      Status:  new       
 Priority:  major    |   Milestone:            
Component:  Fawkes   |    Keywords:  BlackBoard
---------------------+------------------------------------------------------
 Often it's necessary to have a timestamp in the BlackBoard for example to
 tell when some specific data has been retrieved or calculated. An example
 that comes to my mind are the new feature classifiers that take a long
 time to compute. Here you actually need the time when the image was
 recorded that is being worked on.

 Additionally interfaces should get a general timestamp that can be used to
 query the last change of the interface. It should automatically be site
 during {{{Interface::write()}}}. This would also allow for a
 {{{Interface::has_changed()}}} method that can be used if the interface
 has been changed since the last retrieval to decide whether it's worth to
 compute results from the data.
