Renamed "committers" to "team".
Removed references to partial commit acces.
Introduced a technical board.

Extended the scope of the core team a bit (depending on your current
perspective on that scope).
Documented current roles.
Left formal decisions up to the technical board.

As the core team grows towards 50 people, it isn't reasonable to give
everyone veto rights anymore.
Adjusted 'internals' docs to the new organization.

Most of these changes are about using the correct vocabulary -- "core
team member" vs "core developer/committer" and adding internal links.
Removed references to well-known political systems.

Some cultures can't handle these words.
Merge branch 'team-organization'.
