* Added code to support direct addition and replacement of component
  alias objects into libraries.
* Removed temporary strings used to add and remove alias objects.
* Libraries only store alias objects, components now accessed thru alias.
* Simplify library API for adding, removing, and replacing components.
* Updated edit component in library dialog and library editor to reflect
  component library object changes.
