Always advertise to the cluster when we have a peer even if we have also initiated handoff. This might be the cause of the warmup problem -- will test later. At the very least it should not hurt anything due to pick-latest logic and the fact that cluster members with only suboptimal paths do not respond to WANT_PEER.

VERSION 0.6.7: revert change for GitHub issue #20
...
This will have to be thought out more. The old version worked fine 99% of the
time so we'll revisit this.

Fix several things:
...
(1) The changes to path learning in the two previous releases were poorly thought out,
and this version should remedy that by introducing PROBE. This is basically a kind of
ECHO request and is used to authenticate endpoints that are not learned via a valid
request/response pair. Thus we will still passively learn endpoints, but securely.
(2) Turns out there was a security oversight in _doHELLO() that could have permitted...
well... I'm not sure it was exploitable to do anything particularly interesting since
a bad identity would be discarded anyway, but fix it just the same.

Get rid of DBM, which technically is a case of YAGNI. Supernodes will need a way to save identities, but that can be a different feature. Regular clients do not really need a permanent cache (yet). When/if we do need one we can do it then. Until then it only caused problems.

Clean up some routine stuff like pings, and stop keeping links open forever even if there are no frames passing between them.

Each peer now tracks the last time it announced multicast LIKEs independently and does so frequently enough to prevent expires. Also add a multicast debug facility for use on the testnet.
