[crossfire] Time delay in maps

[Kevin Zheng]

Hi,

I'm trying to implement time delay in one of the maps I'm working on.
Unfortunately, I have no idea how to approach this. I suspect I have to
do something in Python, but I've never done this before, either.

Basically, a magic ear will activate a connection, which needs to start
a timer. When the timer runs out, it should activate a different
connection that opens a door.

Any suggestions?

Thanks,
Kevin Zheng
