ifSpace: Save-Progress Feature

Hi all, there is a new update to ifSpace.net that allows logged-in users to save their progress to any game they are playing (up to 3 separate saves per game). So now it is safe to build longer form games/stories without fear of the user not finishing and not being able to come back.

I just pushed this feature to the site today and did as much testing as I thought was necessary to feel confident making it live. But if anyone else tests this and finds something that needs fixed/improved, please let me know either here or somewhere else.
