Added MIME tpe for WonderBrush images

The MIME type that's created by WonderBrush contains an out-of-date
sniffer rule. Archived BMessages used to start with '1BOF', now it's
'HMF1'. That's why newer WonderBrush images aren't identified as such.

The new sniffer rule should detect both old and new files.
