Not working when File system (admin/settings/file-system) is set to private

Hi,

this module is not working properly when file system (admin/settings/file-system) is set to private and File system path is set to path not reachable by http requests. Module saves js snippets in that directory but then when js files are included in drupal pages, they are not loaded, of course.

I tried to make a quick hack and change $directory variable in js_injector.admin.inc (lines 213 and 226) but no success.
