The idea with the image registration is that you register a dictionary 
with _name_ → _path_ pairs and in your pop-up description you use the 
symbolic names.

The advantage of this is that we will only create one `NSImage` per path 
and the popup menu definition can be simpler, i.e. using `symbol` 
instead of `/Users/«name»/Library/Application 
Support/TextMate/Managed/Bundles/«some 
bundle».tmbundle/Support/symbol.pdf` for every single menu item.

Though regarding the former, the command could be updated to 
automatically “register” any image provided as a full path (possibly 
with its hash value to facilitate re-use of images).
