Fix "undefined" error + Logged out options

I had hoped to get pools working with this update since Albert has implemented a way to retrieve a series of posts by their IDs, but being tied up with work for half the day nuked that. Pools should make for a 3.0 release. This is just a "2.4".

* The "undefined" error for older versions of FireFox that didn't support outerHTML should be fixed now.
* When logged out, the resize and similar options should now be available. This also fixes the "image_resize" option when logged out.
