Tweaked room name color
Players with captured input appear as 'EDIT' status
Tweaked how we handle MPI-enabled messages

It's generally more convenient if ParseProp nee HandleMPI does the is-
prop-set and is-result-empty checks and I'm not sure why I didn't do this
before
Fixed DARK flag misbehaving, mostly

There's still an issue with DARK players and objects being invisible to
wizards in room contents, but I need to sort out what the fuck I'm gonna
do with locks before I can feel comfortable fixing that
STICKY objects now get sent home when dropped
Fixed 'take' and 'drop' messages not excluding the player
