[tor-dev] Note on my GPG key update

[Nick Mathewson]

Hi! Please see

https://people.torproject.org/~nickm/key-transition-statement-2.txt

for information on my updated GPG key.  Thanks!

(I wouldn't ordinarily send this here, but this new key signs the Tor
source and tags these days, so it's a good idea to make sure people
know about it.  The most recent releases were signed with both my old
key and my new key: this is the last time that I'm planning to be
doing that, however, since it seemed to confuse a lot of software.)
