Improve the display of role labels

Reported by direct email to me:

You implemented in Braille Extender the roll editor, but there is another disadvantage of braille representation in NVDA which has to be overcame. If I get an attachment for instance, NVDA says and writes in braille “has attachment.” But other screen readers such as Jaws or Cobra could separate speech and braille message. In Cobra for instance in braille was only shown “atm” hor attachment. It could be great if something like this will be possible also in NVDA via Braille Extender.

I would add that flags like unread message can also be shortened
