DFW in multisite needs to check media_buttons

Alternative would be to trigger #add_media, which seems to allow some things, but I don't really know what.

Replying to nacin:

Maybe something along these lines in onclick handler:

(jQuery('#add_image').length ? jQuery('#add_image').click() : jQuery('#add_media').click());return false;

Alternatively we can make the Insert Media button in DFW open the Add Media popup on ms if the Add Image button is disabled (the default), as suggested by @nacin.
