Greek Language, wordpress 4.0

In order to make the greek po and mo files, your plugin, gives the options of el_EL and el_GR for Greek users (I havent tested for Cyprus-Greek which you have an option.

The problem is that wordpress 4.0 allows you to change the language from the admin panel but the option is only
el.
After a couple of tries I found that if you create the files as el_EL and then manually rename them with an ftp client as el.mo and el.po instead of el_EL.mo and el_EL.po then the translations work correctly.

Please update your plugin accordingly since if you want to add translations to your theme, then you either have to create it from the beginning or alter the file with PoEdit or similar software.

Thanks !
