SStoring third-party libraries outside the upgrade path

Definitely best practice for all libraries that cannot be included on Drupal.org due to GPL or other reasons.

Dan discovers in the FCKeditor WYSIWYG documentation

Extract the archive and copy its contents into a new folder in the following location:
sites/all/libraries/fckeditor

So the actual library can be found at:
sites/all/libraries/fckeditor/fckeditor.js

Sweet! If only they were all consistent!
