[Done]: Restore factory defaults.

I recently made the mistake of pressing this button in the config section which resulted in me locking myself out of the admin section. Would it be possible to add a warning after you press this button along the lines of  "You will loose all your current settings. It is a good idea to back up your database before proceeding, Would you like to continue Y/N"

Luckilly, I had recently done a backup.

You're right: a better warning message is needed. Moving thread accordingly.
