Pull Request for New Issue.

Summary of Changes

When you have multilanguage status module active the modals are not correctly displayed because the admin status bar as a higher z-index.

That z-index is putted there by mod_multilangstatus.

This PR removes that forced z-index.

Testing Instructions

1. Use latest staging with admin multilanguage status module enabled
2. Try to do a batch (in article for instance) or any other operation that results in a modal
3. Check the admin status bar is not darkened like the rest of the page
4. Apply the patch
5. Do step 2 again, you will see now the admin status bar it's darkened like the rest of the page

Please notice that this only solves the z-index problems with the status bar. The tooltips not appearing in batch modals are another issue related to mod_multilanguage but not related to z-index.
