Split the html and js into seperate files, implemented a title screen, began work on menu.

- Added a google fonts style sheet for menu fonts.
- Added STATE_ and DEBUG_ for new STATES (TITLE and MENU) and added menu states, which are only used within STATE_MENU. They have not been used to implement the menu yet, but the plan is to use them.
- Menu options currently display all right, but need some mouseover interaction and need to make submenu pages.
