Bug#636783: TC constitutional issues

[Ian Jackson <ijackson@chiark.greenend.org.uk>]

Briefly, mostly for my own notes:

 * 2:1 supermajority for TC overrides should be abolished (seems
   we are probably agreed on this - speak now if not)

 * FD threshold needs to be >= always, not >.  Requirement to get
   >> 4/8 voting X > FD was exploitable and bad news.

 * Possible minimum discussion period for TC resolutions.

 * Clarify ownership of resolution draft versions; what we actually
   did in the end for the 2nd real vote is clearly what the
   constitution intends but it's hard to see how this works in the
   actual text.
