0.1.5c bugfixes

Thanks to Rhoden for the shout-out on the latest chapter of SSG, it's been an explosion of activity here, and thanks for everyone who has commented here or in the SSG discord telling me about bugs. No new content here, just fixing broken things. I would recommend a new save file because of some back-end changes, but hopefully that won't be the case for most of my updates.

• Fixed bug with Axe Mastery not gaining skill levels. That was a big one.
• Fixed bug where Regeneration skill could not be learned
• Fixed bug where Mine guard could be interacted with multiple times and walked through walls
• Fixed bugs around entering rooms in the Harris house. Mr Harris no longer yells at you from another building, and you no longer need to ask permission to leave a room, or to enter a room you already were allowed to enter before. The potion in Emmy's room no longer respawns if you leave the house and come back.
• Added some in-game hints for the status book and how to comport yourself in combat.
• Probably one or two little bug fixes I forgot to document.
