[dev] custom bottons in Horde_Form

[Duck]

It is possible to add a custom button in Horde_Form that is not a submit 
bottom? I would like to add a custom button to quote the message body 
replaying to a comment. So the replay form show up empty, and the original 
message body is copied with JS only when the user chooses it. I quess I must 
classicaly extend the renderer. Or maybe is better to extend the htmlHelper 
JS?
