FIX: sleeping monsters attack on retreat

Fixed.
Tome of Briar Roses

This tome puts every to sleep.
Also ensured that the caduceus and Morphean grenades only put sleepers
asleep.
Non-sleepers

Nameless horror and abyss of the soul never sleep.
Waking up sleeping player

The dream code should replace this.
Change retreat/run text for sleeping

When you move through rooms with only sleeping enemies, the usual prose
wasn't the best.
