 This ticket contains the core changes needed for more robust support for
 site wide level plugin activation in WordPress MU.

 The ticket this relates to is here:
 http://trac.mu.wordpress.org/ticket/1101

 By filtering the active_plugins array, we can inject site wide activated
 plugins into all blogs at include time. This will also allow for site wide
 plugins to correctly run though activate_ and deactivate_ hooks. This is
 important to allow the plugin manager to correctly handle site wide
 plugins on first install or upgrade.

 There needs to be a change to the deactivate_plugins() function to
 accommodate for the fact that site wide plugins will not exist in the
 $current plugins array.

 array_search() will return a value that is interpreted by array_splice()
 as 0 (zero) when a plugin is not found. This will then perform an
 incorrect splice on the $current array and cause many problems. By
 performing an identical check on the array_search() result we can ensure
 that this doesn't happen.

 Patch attached for review and testing.
