Maps created with older versions of Tiled may crash

Maps created with older versions of Tiled may crash applications using tilepix, as some of the required file attributes may be missing or have changed. Check attached example map, that will crash application with a division by zero error when loaded due to missing columns attribute in tileset element.

Thanks for spotting this @svera - what version did you create the attached map with?

I suspect the 'fix' for this will be to simply specify a minimum supported version.

@bcvery1 don't know, it was a map downloaded from the Internet.

I also would check if columns is 0 and return an error in that case.
