Added more up-to-date data

1) Pulled the current transliterations of all the texts from ur3_20110805_public.atf
   from the cdli website, and put them into ur3_20140114_public.atf.  There are a
   number of texts that have been removed from cdli's database, along with more being
   added, so this new data shouldn't be thought of as exaustive set of all Ur III
   texts.

2) Moved *.atf to the new "data" directory

3) Updated src/cuneiform/Parser.java to use data/ur3_20140114_public.atf
