IRON-GATE-F doesn't check if the gate is already open

[eriktorbjorn]

>EXAMINE GATE
The iron gate is closed.

>CLOSE GATE
It is too heavy to move.

>REZROV GATE
The chains of the iron gate fly into the air and vanish. The gate flies open and
a blast of cold air fills your lungs.

>OPEN GATE
The gate is secure; it cannot be unlocked.

>EXAMINE GATE
The iron gate is open.

>REZROV GATE
The chains of the iron gate fly into the air and vanish. The gate flies open and
a blast of cold air fills your lungs.

That's because IRON-GATE-F has the same responses to open, close and REZROV, regardless of whether the gate is closed or not.
