Port Fixed

There are a couple of things that need to be changed.
1. When the door is closed and your at bank the bot clicks on the
opposite side of the furance area. I suggest making the area smaller so
that the bot clicks in the furance building. This will allow the bot to
open the door.
2. Go back to the old walking methods.
3. You might want to change where you put the OpenDoor() method. I put
it in both the smelt and bank method because otherwise selectloc was
returning null for me.
4. I changed the methods a little bit in order to handle the door.
Pretty much a special case for Port otherwise it'll try to keep clickign
the furnace without hitting the open door method. :)
