Expand and Refine Membership rules

[MylesBorins]

The first commit is a structural change of where we define our concept of "quorum" for the sake of consistency. AFAICT this does not change any of our current rules or expectations.

The second commit does the following:

• Introduce Membership Types
  • Active Member
  • Observer
• Define roles
• Define process for applying for membership
• Define process for changing membership status

One important thing to note, the way I defined things here Observers full participate in the Consensus Seeking Process. It is only when determining quorum and voting that there distinction in Membership. The intention is that Observers will be able to fully participate in discussion and reaching consensus including the ability to object to anything.

Do people think it makes sense to simplify "Active Members" to "Members".

We could also have "Collaborators" instead of "Members"
