Saved games implemented

A few of my playtesters lost their progress while playing the game, so I implemented a save game feature. To use this feature, all you have to do is nothing. The game will automatically save as you play, and then if your browser refreshes or you close the page, you will be prompted to continue your game where you left off.

I've been working on a lot of odds and ends lately without as much effort into finishing the Captain's programs, but she's getting cranky and wants her programs done so I will probably be getting back to that soon.
