Custom certificate (plugin)

Hi Chardelle,

I think I'm almost there...

As of the latest copies of 1.9 (official) and Certificate I downloaded today, the locking appears to be working correctly for me now.

I've not been able to test the changes made for addslashes_object just yet, as I'm getting a new error when I click on the button to receive the certificate. I've filed this in the Tracker under CONTRIB-317.
