Rock door in Kuftal Tunnel now opens or closes based on current weather

A working implementation of the Rock Door as described in:  Kuftal Tunnel rock https://github.com/DarkstarProject/darkstar/issues/365

I used info from [FFXI wiki](http://wiki.ffxiclopedia.org/wiki/Talk:Kuftal_Tunnel) to set the rock to come up during wind and gale weather and to be down for everything else
