Add the "votes" header property.

On polls, this is the maximum number of votes per ballot in response to this
poll (0 is the same as 1).
On ballots, this is the bit-field of votes submitted by the user (e.g. bit 0
set is a vote for answer 1, bit 1 for answer 2, etc.).
For normal messages, this field has no current use.
