Added preliminary docs for the new configuration objects.
Updated ApnsConnection and PushManager docs to reflect the new configuration objects.
Updated notes on PushManager construction in the README.
Good news: at least some of those null checks work.
Updated docs for classes affected by the introduction of configuration objects.
Added unit tests for copy constructors for configuration objects.
Restored inadvertently-clobbered PushManager tests.
Added unit tests for null checks in ApnsConnection and PushManager.
Minor tweaks for style and readability.
