This change adds support for the attach event in scripts.

Browse Source 
[1] Added a new OnAttach event to Scene/EventManager
  [2] Hooked up existing attach event handler in XEngine.
  [3] Modified SceneGraph and Scene.Inventory to trigger
      attach events at the appropriate places. I was forced
      to distribut the changes across two files because of
      the way attach processing is distributed across the
      two files.
  [4] In the case of RezSingleAttachmentFromInventory it is
      necessary to handle event scheduling in a special way.
      There is no synchronous path available, so the fact
      that this object is attached, and who it is attached to,
      is cached when the ScriptInstance is created. When
      the script is started, the attached handler is driven
      after on_rez (but before changed, this should be reviewed).
