/ROOM EXFLAG

These flags are put in a direction in a room for their various effects.

Syntax:

 /room exflag <dir> [+|-]<flag>

Example:

 /room exflag up hidden      [makes the exit up hidden]
 /room exflag east -climb_up [removes the climb_up flag east]
 /room exflag west nomob     [makes the west connection nomob]

Available exflags:

PICKPROOF   Makes it impossible to pick the exit in this direction.
HIDDEN      The exit becomes hidden.
NOMOB       Mobiles will not move in this direction.
CLIMB_UP    You must climb to go up here.
LOCKABLE    The exit can be locked. Without this flag, the exit can
             not be picked either.
CLIMB_DOWN  You must climb to go down here.

The reason for climb_up and climb_down is that when you try to
pass a climb_up but fail, you will end up in the room you tried
to climb from, but if you try to climb down but fail, you will fall
and land in the destination room anyhow (but take damage from the fall).
