user/*/imce should be reported as admin path

Imce adds a file browser tab to the user/* paths but doesn't report it as an admin path which causes the site to switch in and out of the overlay when going from edit to file browser and back.

Since user.module reports all its paths as admin paths:

function user_admin_paths() {
  $paths = array(
    'user/*/cancel' => TRUE,
    'user/*/edit' => TRUE,
    'user/*/edit/*' => TRUE,
  );
  return $paths;
}

I'd think that it would be more consisten if imce did as well:

function imce_admin_paths() {
  $paths = array(
    'user/*/imce' => TRUE,
  );
  return $paths;
}
