[jsikulifut13] added ocr support. 
implemented intelligent sleep between relist cycles by using ocr to read
the time remaining on the head card. 
refactored robot classes into engine subpackage.
ocr is jar and dll - added to branch. jar is handled by maven using
install into local file repo. dll is in resources and is pointed to by
ocr at run time.
ocr is trial so annoying pop up is shown everytime it is launched. used
sikuli to automate its escape :)
that's all folks!
