LightUp Fix

[rspacerr]

Description

I'm still working on TreeTent fix but I figured I might as well get the LightUp fix out. Added support in Puzzle Creator and should be able to save files.

Closes #372

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Enhancement (improvement to an already existing feature)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

How Has This Been Tested?

I opened Puzzle Creator, selected LightUp with bounds of 7x7, placed a black tile and was able to successfully save the file.

Your changes have a lot of merge conflicts. Please fix them.
Additionally, please be careful of what files you are pushing. There are 114 files changed in this PR and after a quick look, the majority of these files don't have any real changes (my guess is the IDE you're using has different line endings from what this project uses).
