squid3 port file has no --enable-http-violations option or variant

[essandess (Steve Smith)]

The port file for squid3 does not have an option to set the --enable-http-violations configuration flag. This option is necessary for squid to edit HTTP headers.

It is possible to add this flag by hand with the edit sudo vi `port file squid3`, and adding it manually under configure.args. This works, but obviously any update to the squid3 port file will wipe it away.

Would you please consider adding the --enable-http-violations to the squid3 port? My own rank-order preferences to accomplish this are:

1. The flag --enable-http-violations is a default in the standard {{squid3}}} port file.
2. Create a squid3 port variant for --enable-http-violations.
3. Add a user-configurable config options list that can be modified on the port command line call.
