Changelog:

Version 1.1.1
Reworked version to more actively reflect the scripts current state.

Added Error checking if you try and open the script with out an active project open first.

Removed a bug that would cause the user to crash when selecting the top part of the tile (just about to slope) and the width selected was not in multiples of the tile width.

It is recommended to update to this current version as the bug that was found could be quite a pain and lock things up while stuck D: Luckily no one had found the bug (that I know of) but it is now fixed so download this version just to be safe!
