Fixed Facebook Open Graph Logo title in properties

[Steve F]

Since more and more applications are using open graph meta data (Skype being one) I think the style property for the Facebook Open Graph Logo title could be changed to simply read Open Graph Logo. May be late in the game to change it but this thread made me think it would be less confusing when referencing it.

I've changed this now. Only real hesitation had to do with existing support stuff, as people may look for "Facebook" and not find it now, but this is a more accurate name.
