compress each hell branch to single floor

[papilio]

please

current Geh,Tar,Coc,Dis:1-6 are pointless

[Fingolfin]

Reducing them to a single floor is probably excessive, they do help get a feel of Hell effects and monster types before tackling the boss floor

I want them to compress each branch two floors, then stack all nine hell floors as one branch.

Also I would remove the quick-escape feature of hell stairs, though I'd provide an exit portal on Hell:9
