From 6c434e8b8e420c76f86ba6605e98426fddca5031 Mon Sep 17 00:00:00 2001
From: Jeremy Kemper <jeremy@bitsweat.net>
Date: Mon, 7 Nov 2005 08:09:38 +0000
Subject: New configuration option config.plugin_paths which may be a single
 path like the default 'vendor/plugins' or an array of paths:
 ['vendor/plugins', 'lib/plugins'].  Plugins are discovered in nested paths,
 so you can organize your plugins directory as you like.  Refactor load_plugin
 from load_plugins.  Simplify initializer unit test.  Closes #2757.
