Adding in my most important feature yet

This week I've added in a save, dialogue and new letters meta data systems and I've got nothing to show for it! A lot of this work is foundational to getting the new demo working. The save system allows us to be able to have unlockables. The dialogue system allows us to easily author cutscenes. The meta data system allows the progress from tombs to be detailed post tomb exploration. The next step is getting the Henry Pepper's chapter working!
