V0.5 Saving/Loading and other changes

This update is a bit later than I had hoped but there are some significant changes. Instead of dumping you straight into the game there is now a startup menu to start a new game or load a saved game. In fact the biggest change is the introduction of a saving and loading from the pause menu. Currently there is only one save file, so every time you save it overwrites the previous save. I am working on an interface to have multiple saves, but its not quite ready yet. However the save system does seem to working well based on my tests.

Another change is that enemies actually move around, instead of staying in one spot and waiting for you to bump into them. Not the most complicated behavior, but it'll do for now. Also, some enemies can inflict negative statuses on you. There are items for sale, and sometimes they can be found after winning a battle, which cure negative status.

Another big change is that there is a basic short questline which can be followed. Its not much yet, but its a start, and the save system seems to properly keep track of progress on this quest. If you get far enough in the questline, you can even reach a new area that was not in previous versions of the game.
