Generate Map feature added, v1.3; er 1.31

Added a Generate Map feature to the menu. It's not perfect by any stretch, but it's a start, and might be helpful for inspirational purposes of map making.

Thanks, and enjoy!

EDIT: ARGH! I IMMEDIATELY FIND BUGS JUST AFTER I UPLOAD, C'MON NOW, GIMME ONE SECOND

EDIT 2: Okay, I have updated the files attached to v1.31, ie fixed some rather obvious typos in my code I should've picked up but I didn't do obvious testing bits, bleurgh. Alas. Please reach out to me if you suffer crashes of any sort or anything, I do want my program to be stable for people. Thanks 💙
