memcached can be exploited via UDP. This disables it by default.

Optionally could make it a default var memcached_port_udp: 0 but maybe it'd never be used.

Oh I meant to do that. Added.

Also added changelog entry. This is technically a breaking change although I doubt anyone is actually using the UDP feature.
