Add Shortcut in the Shadow Keep

[Jonhmarcus]

I am not sure how easy this would be to implement, but I always thought it was strange that there was no shortcut between the part of the Specimen Storehouse accessed from the front entrance and the part accessed from the Church District. However, there is this currently unopenable door that would connect the elevator that leads to the Gaius arena with the interior of the Storehouse, which for some unfathomable reason was not used for a shortcut. Basically, the door on the inside of the storehouse should be one of those doors which says "this door does not open from this side" when accessed from the interior of the storehouse and opens from the other side instead, connecting the two areas together. I think this would improve the sense of interconnectivity in the level by a significant margin. Pictures of both sides of the door attached.
