API doesn't need to be passed hashed emails

[ndbroadbent]

I think the api has changed, and no longer needs a hashed array of emails. For example, the following code works now:

def use_user_image!(image_hash, emails)
emails = [emails] unless emails.is_a?(Array)
hash = call('grav.useUserimage', :userimage => image_hash, :addresses => emails)
expire_cache!
return hash
end

I would have submitted a pull request, but I didn't understand your 'dehashify_emails' method. So I've just hacked it up for now.
