amending movebrief to show all visible exits

[ninja]

So, as a screen reader user I have movebrief turned on and this feature greatly helps by condensing the information that is most relevant when travelling. But the info it omits that is crucial when trying to travel quickly is the other possible exits other than, the cardinal directions. I mean the other possible visible exits shown when using the exits commands.

I think it would make good sense to include these other exits (e.g. "arch, gate, building,etc.") when using movebrief.
