Patch 1.0.6

A couple of other oversights have been found and fixed.

• The Hikari Gate now makes sure the key is in the player's inventory before trying to remove it once every required item is collected, preventing a game crash.
• Collision was added on the eastern side of Purple Lake. I have no idea how I missed this.

It's nothing major, but it was important enough to me to warrant another patch, so here you go.
