Feature Request: Set Ruler Origin Location in Photoshop

NOTE: I can't edit my previous post, it just comes up with a blank field (I have tried two different browsers on the Mac).  Strangely, I can edit this post, go figure!

A revised 1.2 version is below, which fixes the issues with the radio button groups in the 1.1 code!
