I'm calling the program "Mapster" :-)

I'll consider the fatalsToBrowser, it'd give the users more of a clue about what is wrong when something goes wrong than just a white screen.

However, when something goes wrong, it's usually because I'm fooling around with it, and I'll have it fixed in a matter of minutes, so it might not be that necessary.

But thanks for your input. Also, I've fixed some more bugs. I'll update the code soon.
