Listener/Callback icons - help needed

[Andrus Adamchik]

Per CAY-900 we now have callback GUI in the Modeler. It is still  
being polished, but the functionality is there.

Can somebody with the graphic skills (Malcolm, Ari?) help us with the  
buttons. There are placeholders checked in for "add method", "add  
listener", "remove method", "remove listener". The simplest way to  
create the icons is by adding a letter (M or L) on top of the  
existing icon-trash.gif and icon-plus.gif, but maybe there are other  
ideas.

To see what I am talking about, build Modeler from SVN, and check  
Callback and Listener tabs for DataMaps and ObjEntities.

Thanks
Andrus
