Added dog companion, and building frameworks for future level expansion (v0.13)

• There is now a dog in the game that you can befriend and bring with you on your journey. Keep it fed and healthy or it will cease to be your companion! Pictured above.
• Added a lighter to the game to help light your way. Also pictured above.
• Changed many dialogue lines and fixed a few bugs

I've set up a rudimentary system for loading playable spaces and unloading spaces that the player is leaving. I plan on adding several zones that will be required to travel through to finish the primary quest of the game (returning the human home.) The second zone is currently accessible, however it is in a very early state and there is no content in it to complete. The characters you befriend should follow you through different zones, but there is some wonkiness that I'm looking into the cause of.

That's all for this update. Try the update and befriend a dog! If you have any feedback, please do not hesitate to give it in a comment, message, or thread.
