File uploading is broken!

It looks like the settings reworking broke file uploads!

<b>Fatal error</b>:  Uncaught Error: Cannot use object of type stdClass as array in /srv/wikitle/www/index.php:2808

I've fixed that first issue with the mime mapping overrides, but there's apparently a second issue in the logic that checks to make sure that the Files directory is created. Apparently it didn't support $env->storage_prefix..... That really should have been detected earlier! I should upgrade my testing environment...!
