Quality of life update

After almost two years of dormancy, SIC-1 has been updated with many "quality of life" improvements.

The most visible change is that the graphics have been subtly improved in a few places (charts, scrollbars). There are also now menu options for toggling fullscreen and changing the zoom factor (of course you have always been able to use browser shortcuts/settings for these).

Additionally, there have been many small, but important, improvements under the hood, including improved testing of solutions, more consistent behavior, purging of invalid scores, and many bug fixes.

Hope you enjoy the game! If you run into any issues, please post a comment or email sic1@schemescape.com.
