Admin tools development/SUL Audit

In order to effectively plan for the final Grand Unification (required for truly global features), we need to determine the current state of SUL.

Status
2013-04-11 - Unifying non-clashing accounts.

Goals
As a first step, we want to determine the following metrics: Once we have access to these numbers, we need to determine a strategy for unification which will involve breaking down the above by
 * 1) Number of global users
 * 2) Number of local users without a global account (can be easily unified)
 * 3) Number of local users that clash with another local user (no global account involved)
 * 4) Number of local users that clash with a global user
 * Users who have edited in the last 3/6/12/24 months
 * Users with logins in the last 3/6/12/24 months
 * Users with a confirmed email address
 * Users without a confirmed email address
 * (anything else?)
