* Corrected sym link creation in debian/postinst. (LP: #533989) * Added ampache.preinst to remove /etc/apache2/conf.d/ampache so the sym link name mismatch will not affect upgrades. * Added purge check to debian/ampache.postrm so webserver will be restarted on remove and purge. * Added additional checks in debian/postrm to remove both /etc/apache2/conf.d/ampache and /etc/apache2/conf.d/ampache.conf. this way the package is completely purged.
