IMCE Inserts are not respecting insert path settings or insert plugins

Problem/Motivation

The base_path of the site is always prepended to the path of the inserted link when linking to a file using IMCE. There was a patch for the 7.x-2.x branch but that was closed and this issue was never resolved. See node/1221606.

To Duplicate

Try to insert add a link to a file using IMCE where Insert Paths as: is set to Raw Paths. The base_path of the site is always prepended to the inserted link.

Proposed resolution

Need to modify the Drupal.linkit.IMCECallback callback so that the links that are inserted according to the Insert method settings for the given profile. Maybe something like this:

Drupal.linkit.IMCECallback = function(file, win) {
  var instance = Drupal.settings.linkit.currentInstance;
  var data = {
    path: file.relpath,
    attributes: {}
  };

  if (instance.helper == 'field') {
    link = win.imce.decode(Drupal.linkit.getInsertPlugin(instance.insertPlugin).insert(data, instance));
  } else {
    // TODO: Not sure why the above doesn't work for editors...
    link = Drupal.settings.basePath +
         Drupal.settings.linkit.publicFilesDirectory + '/' + file.relpath;
  }

  Drupal.linkit.populateFields({path: link});
  win.close();
};
