Change/Retcon: Shadgard mine workstalls/access removed

[Rias]

In a retcon move now that the Coalition has its own HQ (and the wilderness is larger than the 3 rooms it used to be), Traders' workstalls and eastern tunnel access have been removed from the Shadgard mine. Any items or mounts in these workstalls have been moved to the newer workstalls in the Coalition HQ, northwest of Ebon Pass.

As stated before, this is a retcon - you may assume in-character the Shadgard mines have always belonged to Shadgard alone, and not the Western Coalition.
