[MlMt] Inline images

[Jeffrey Horn]

Supposing I've blocked inline images, but not checked the option for 
"unless explicitly marked as junk". Does MM indiscriminately block all 
images in the selected boxes?

I suppose I could just check the box and create a custom keyboard 
shortcut for marking "Not Junk". I like the idea of blocking images 
unless I choose otherwise, but clicking "Not Junk" breaks my keyboard 
flow.
