Also exclude upstream when picking supernode for multicast propagation, to not bounce back and forth to the same supernode.

0.3.0: BREAKS PROTOCOL BACKWARD COMPATIBILITY
...
This version is not compatible with versions prior to 0.3.0, so
'git pull' and restart if you are following the alpha.
Changes from 0.2.5:
- All multicast frames are now signed by the original sender. This
will permit very efficient and fault tolerant rate limitation
across networks, and imposes a kind of "hash cash" cost on those
who wish to flood the network by forcing them to keep regenerating
new identities.
- Simplified peer last unicast / last multicast accounting.
- Improvements to multicast propagation algorithm to achieve better
coverage with less redundant messages.
- The bloated Switch class went on a diet, having packet decoding
broken out into PacketDecoder and multicast propagation algorithm
broken out into Multicaster.
- Multicaster is implemented as a template mockable class to permit
future simulations of huge scale multicast using the actual code
instead of mockups in another language.
- Introduced a faster non-cryptographic random source for things
like multicast propagation and address choosing.
- Some code cleanup, removal of outdated comments, etc.

Simpler variant on multicast propagation algorithm seems to perform better by being less deterministic. May also be faster.

Several things:
...
(1) Probable fix for issue #7 and major cleanup of EthernetTap code with consolidation for all unix-like systems and specialization for different flavors only when needed.
(2) Refactor of Buffer<> to make its members private, and Packet to use Buffer's methods exclusively to access them. This improves clarity and means we're no longer lying about Buffer's role in the code's security posture.
(3) Add -fstack-protect to Makefile to bounds check stack variables.

Send HELLO instead of NOP for NAT-t in order to measure latency always. Also prevents a race that can cause the first NAT-t to fail where the NOP arrives before the WHOIS reply from the supernode. Now NAT-t initiators will push their own public keys anyway so that doesnt matter.

Possible fix for issue #4 - segfault in ___removeIp helper function in EthernetTap on OSX -- I think the problem may have been that I was using set::erase(key) while also using an iterator, so now it uses erase(iterator). See if it happens again, cause I could not duplicate the issue. Possible minor difference in STL version.
