iipserver cgi program does not work with standard configuration of Apache 2.4

[Ulf Mehlig]

The location of the iip image server cgi program is located in /usr/lib/iipimage-server/. However, the Apache 2.4 standard installation on Ubuntu prevents scripts from running outside /usr/share and /var/www by configuration in /etc/apache2/apache2.conf. To run http://127.0.0.1/iipsrv/iipsrv.fcgi successfully, it is necessary to change the path of the cgi program or to adapt /etc/apache2/apache2.conf, e.g. by including

<Directory /usr/lib/iipimage-server/>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

I think packages like iipimage-server should work "out of the box", or at least feature a README.Debian instructing the user properly -- by running the suggested basic test in this file, one ends up with "Access denied".
