[zeromq-dev] ZRE/Zbeacon improvement proposal

[Pieter Hintjens]

I've made the same changes to Zyre, https://github.com/zeromq/zyre/pull/134

Also updated the ZRE RFC to cover this: http://rfc.zeromq.org/spec:20
-- it's a backwards compatible extension so I modified the existing
RFC event though it was tagged as 'stable'.

Tested, and it seems to work.
