Increase speed and fix formatting of messages in nomoveon.kod.

-Spacing/grammar changes.
-Removed repeated check for $ in SqFD (SqFDT handles this; SqFD isn't used yet).
-Use piRow/piCol instead of Sending to self for them (variable is faster).
-ReqSomethingMoved checks for $ row/col on what before checking distance (stops mobs spawning on top of each other).
