Detect editor in an installation profile libraries directory

Currently, the only libraries folder searched is /sites/all/libraries. However, installation profiles can also contain libraries, and I think the currently installed profile should be searched as well.

This can be done in a couple of ways in ckeditor.lib.inc _ckeditor_script_path():

1. Utilize the libraries API

         <?php
            elseif (file_exists(libraries_get_path('ckeditor') . '/ckeditor.js')) {
              $jspath=libraries_get_path('ckeditor') . '/ckeditor.js';
            }
         ?>
       

Use core's built in install_profile variable

      <?php 
        $installed_profile = variable_get('install_profile', 'default');
        $profile_path=drupal_get_path('profile', $installed_profile);

        elseif (file_exists($profile_path . '/libraries/ckeditor/ckeditor.js')) {
           $jspath=$profile_path . '/libraries/ckeditor/ckeditor.js';
        }
      ?>
    

I like the first method, but that does introduce a dependency on another module. I will post a patch for the second method.
