Explanation of what is in the pubkeys table:
The hash is the RIPEMD160 hash that is encoded in the Bitmessage address.
transmitdata /was/ literally the data that was included in the Bitmessage pubkey message when it arrived,
except for the 24 byte protocol header- ie, it started with the POW nonce. Since protocol v3, to maintain
backwards compability, the data format of the data on disk is staying the same even though the wire format has changed.
time is the time that the pubkey was broadcast on the network same as with every other type of Bitmessage object.
usedpersonally is set to "yes" if we have used the key personally. This keeps us from deleting it because we may want to
reply to a message in the future. This field is not a bool because we may need more flexability in the future and it doesn't
take up much more space anyway.
