Added option to show your panel position in unfinished games list.

I want to track how my games are progressing, but it is hard to remember which panel number I got.

I have added this functionality into your script (disabled by default). When enabled, panel position is saved upon submit and then shown on profile page.

A known problem is that it will remember a position incorrectly for games created before the function is enabled. I'm too lazy to fix it now.
