This has been reviewed by merchants, miners and exchanges for a couple of
weeks, and has been implemented and tested as part of the Bitcoin Classic
and Bitcoin XT implementations.

Constructive feedback welcome; argument about whether or not it is a good
idea to roll out a hard fork now will be unproductive, so I vote we don't
go there.

Draft BIP:

  Increase block size limit to 2,000,000 bytes.
  After 75% hashpower support then 28-day grace period.
  With accurate sigop counting, but existing sigop limit (20,000)
  And a new, high limit on signature hashing
