[dev] prefix display

There are a few other places that a folder is displayed and would look better 
(at least to the user) if the prefix was left out.  How about an 
IMP_folder::label() function that accepts the fully qualified name strips out 
the prefix and returns just the folder name?

something like:

return substr($folder, strpos($folder, preambleString()) + strlen(preambleString
()))
