DS-1336 - Honour CC 1.5 API

There's no mention on the currently used by DSpace API (v1.5) (or the dev one) to the /classes call:

http://api.creativecommons.org/docs/readme_15.html#locale-xx
http://api.creativecommons.org/docs/readme_dev.html#locale-xx

Looks like they belong to some legacy support.
