updated turtle data files

Hi everyone,

I checked into CVS updated Turtle data files that should eliminate 
numeric short forms in favor of explicit lexical form + datatype 
representations under data-r2/.

Could people who can run most of the test suite take a shot at the 
latest in CVS and report any errors to me? I've done some spot checking 
but am not currently setup to run the full suite (oops, better get that 
in line by next week).

I guess AndyS would be the best one to catch any mistakes I've made, but 
any other reports are welcome!

thanks,
Lee
