[FIX] share: Replace calls to includeTokenReturn with includeToken as includeTokenReturn was faulty and seemed to do the same as includeToken when fixed (was assigning an offset in a string leading to the link being an 'h' char), also, use the same token over and over when not "subscribing" and there is only one.
Also put the SERVER_NAME at the end of the mail subject and make the "return" link look a little better (thanks Xavi)
