Disabling Automatic Synchronization

I completely forgot to mention that it is possible to disable automatic synchronization until I received a question about it.  There are two preferences that control this: Synchronize interval and Initial sync delay.  If you want to disable automatic synchronizing completely, set both of those to 0.  Alternatively, you can just disable all but the first auto sync when you open your Address Book window by setting Synchronize interval to 0.  If just Intial sync delay is set to 0 then there will not be any automatic synchronization until after you press the Sync button and the next sync is scheduled after the interval expires.

There is a Sync button added in the Address Book toolbar that you can use to synchronize manually.

The next test release will have a checkbox to disable automatic synchronization.
