Adding Hebrew translation for the OpenDefinition

Hey guys @ OKFN! 

I've added a translation of the OpenDefinition into Hebrew.

Please let me know if you need anything more. BTW, it should be RTL on the page, but I figured that it's going to be useful even if it's LTR...

Let me know if anything is out of the ordinary @ idoivri [at] gmail.com
