Theme managment

[benji2 at softhome.net]

Hi ! 

Is there any info somewhere about Pidgin theme management ? I found 
something old about GTK themes 
(http://developer.pidgin.im/wiki/Using%20Pidgin#CanIskinPidgin) and more 
recent info at http://developer.pidgin.im/wiki/BuddyListThemes 

I would like to know more about the drag and drop feature. With what kind of 
theme does this works ? I saw something about .tar.gz but I can't remember 
where. 

It would be nice if we can drag a .xml blist theme here to install it. 

Thanks.
