Added autonyms directly to langdb.yaml

* Can add languages not in MW
* Can get rid of foo / bar names which include different scripts
* Can get rid of directionality marks
* PHP scripts to generate the jquery.uls.data.js is now independent of
  mediawiki and moved the scripts to lib/jquery.uls/data
* No pretty printing for the jquery.uls.data.js and added a 'do not edit' comment.
* Related changes in RL module definition and example html
