In many case, the real name of users is printed, in a few other it is the login name.

As the login name still matter (used with most services not part of Savane), it should be seen more often. Also, in some case it would not make sense to print the whole name, especially when size matters (bug big lists) while in other case it is just not enough informative to only print the login name.

I suggest that anytime a realname is printed, the login name get along ; and to leave login name alone when the size matters.

For instance, this task submitter should looks like
Mathieu Roy <yeupou>

It would be an idea to append the @domain, but it will waste space and it is not sure that a Savane installation is set up to provide working user@domain aliases for the outside. So it is best to keep it as login and not create confusion by showing it like an email address.
