Patch for squid.conf template

During testing the "check_squid" script from https://github.com/DinoTools/monitoring-check_squid it came out that with the default order of acl in the squid.conf file the cache_object won't be accessible neither from localhost nor from other networks. The error message in /var/log/squid/access.log is

127.0.0.1 TCP_MISS/200 2614 GET cache_object://127.0.0.1/info - HIER_NONE/- text/plain

The solution is to move the line

http_access deny !web_ports

in the squid.conf file two lines lower.

print("http_access allow localhost manager")
print("http_access deny manager")
print("http_access deny !web_ports")

I've uploaded a patch for the /etc/univention/templates/files/etc/squid/squid.conf template.
