Create journal-of-art-historiography.csl

Hi! I am trying to create a style for the Journal of Art Historiography, the description can be found here: http://arthistoriography.wordpress.com/journal-submission-guidelines/
It is very similar to the existing "Art History" style, but it needs to display the publisher and the Journal titles need to be in Italics. 
I had a shot at altering the art history style here to fit the journal, but I have absolutely no experience with this so I have no idea if it's going to work. Many thanks for further contributions!
