Load unheaded tile maps fails

[remy]

Good catch, I spotted that when I was making the change - because I sneak the map dimensions into the +3dos header so it's easy to reimport, but without the header it doesn't know what dimensions it has.

Obviously it shouldn't blow up like that - I'll fix the import without header, and prompt for the dimensions.

Bit late to reply to this, but now when you drop/upload a headerless .map file onto the tool, it'll prompt for the width (in tiles) and then it'll render it properly 👍
