Pcbnew footprint library table fixes.

* Make footprint viewer work properly with library table.
* Fix bug in Eagle plugin when enumerating footprints.
* Add missing P-CAD plugin from footprint library table editing dialog.
* Fix bug in FOOTPRINT_INFO::LoadLibraries when error occur loading footprints
  from libraries.
