Compare versions of Scripts using Diff Library

[bn]

When developing I often save the whole stack with an increasing version number. When going back to a previous version it can be hard to detect the differences between two versions.
There are probably many solutions out there to tackle this problem.

I used the diff library that is included in LC since version 9 to make a GitHub style diff that helps to show the differences.

This might also be useful to others. Click on the question mark to see a help text.
