[Users] typos in documentation and use_domain question

[Klaus Darilion]

Hi!

In the uri_db documentation (all parameters):
modparam("db_url", "....
           ^^^^^^
shouldn't this be uri_db?

In the group_radius documentation:
modparam("group", ...
           ^^^^^^
shouldn't this be group_radius?

I also wonder about the use_domain paramter in the radius modules.
group_radius has this parameter, whereas all other radius modules 
(uri_radius, avp_radius, auth_radius) do not have this parameter? Is 
there a reason for this?

regards,
klaus
