Greek translation with many new fields translated

-- HikaShop version -- : 2.2.2
-- Joomla version -- :3.2


Hello here is my language file for Greek language for use with HikaShop Essential 2.2.2 and Joomla 3.0
I translated over 50 fields that were not translated and appear in many places in the website (especially the frontend)
Hope you like it.
I will keep updating the language file if I find any more tags that need to be in Greek
