Add logout (sign out) link on the page when using Apache htpasswd authentication

[2mstorm]

Is your feature request related to a problem? Please describe.
When I use htpasswd authentication in Apache to protect AWStats report so it requires password, there is no easy way to log out

Describe the solution you'd like
I found that in order to log out in this case I have to visit link http://logout:[email protected]/ where example.com would be replaced by the domain the awstats is setup on. This is based on (https://stackoverflow.com/questions/1163868/how-to-logout-when-using-htaccess-and-htpasswd-authentication)

It would be nice if the link http://logout:[email protected]/ is included on the AWStats report page under Sign Out, (like
Sign Out)
and then the users can turn on and off option to show link in the config for the AWStats for that domain

I made this work by editing awstats.pl file and adding the line
print "<a href="https://logout:logout\@mydomain.com/awstats/awstats.pl\">Sign Out";
in the HTMLTopBanner function
When I click on the link, my browser forgets the username and password I used to authenticate
