Governance proposals

@devel-chm, @jberger:

I looked over the governance document, and a few items or areas (in my opinion) could use some clarification from a 'where could some sticky points or contention arise' viewpoint.  Would you two be able to comment on the commits?  If there are issues with any of the changes, or if any of the items should be broken out into their own issues for discussion, I am very willing to rework the set of changes.

I tried to keep each change distinct to facilitate commenting.
