#378 whois online block for profile module

[irmtfan]

The user information is very limited.
we just have one smarty: <{$block.online_names}>
we need the ability to show user real name, user website, user email and more importantly some custom made fields in the whois online block.
membership module have a better view but it is very simple.
i think it should be come from a block in profile module.
Currently profile module dose not have any block
