#46: Fix the key instance of the smithy's door

[szapp]

Description

Fixes #46. Make the smithy's door accessible.

Test

Run manual test with test 46. The test has two passes.

1. First function call: The PC is teleported to Stone's cell and the story is advanced to chapter 4.
2. Second function call: The PC is teleported in front of the door.

There are some tests to check off.

• The key shows up in Stone's cell (first pass)
• The key opens the door (second pass)
• The key is still present in the inventory after saving, quitting the game, restarting and loading
• The key is still present in the world (drop it on the ground) after saving, quitting the game, restarting and loading
• The key is still present in a chest after saving, quitting the game, restarting and loading
• The key is gone when removing G1CP and loading (there should be no visible error) most interesting one
• The key is properly re-inserted when re-installing G1CP (note that this only works for game saves where the door was not unlocked yet).

To understand when the key is and is not inserted, the flow-chart may be consulted (or even verified).

I think there is still a problem. When loading a game save twice the door might not be locked again. I will have a look before merging.

I removed re-locking of the door. The reasoning:

When reverting, the door will not be locked again. The reasoning behind this is, that G1CP is only supplying a way of unlocking the door. It's the player that may unlock it. G1CP will only revert its own actions, not the consequences.

I hope we can agree on this.

Do I understand correctly that the key won't fit anymore, but the door remains open, because the player unlocked it before (if he did so)? If so, I don't see any problem as the saves won't be affected.
