Updated to  v1.1

1. Added “Building a Corridor” to Actions section, where it should have been. It’s now combined with a “Connecting Rooms” action into one.
2. Fortress’ max Depth requirements for a Lair increased to 5 instead of 4. Should give an extra layer to "safely" dig in the early game.
3. Clarified the Gate description to make it clear that enemies cannot pass through it. Also, that it's placed between 2 squares.
4. Clarified the Room being auto-enabled when built. No need to enable Rooms after building them.
5. Added a sample game graphic.
