Proposal for how to deal with issues and actions and when to close

We've been having a lot of confusion for when to keep issues in Tracker 
open and when to close them. After discussion in a couple fora I suggest 
we adopt the following principles:

  * If an action item is created to make a document edit that addresses
    the issue, close the issue even before the action item is completed.
    We would need to be careful to review both action items and issues
    when deciding if the plate is clear before key transitions.
  * If an action item is created to make a proposal for how the issue
    might be addressed, leave the issue open so the group can discuss
    the proposal. Once a proposal is accepted, the issue can be closed
    and an action to make the edit created if needed.
