Fixed folder offset issues

Changes

This is a small hotfix release with custom folders not drawn correctly in tree view.
This should fix the offset issues that existed.

Reformatted code, removed background selection colour

Changes

• Reformatted code to align with correct standards
• Removed invalid background colour when folders are selected. Unity does not do it by default nor was there reason to add it manually.

Removed invalid folder validation

Originally, folder validation was added to keep track of texture folders.
This has been removed due to it serving no purpose.

Fixed Folder Preview Sizing

Fixed folder overlay texture displayed with incorrect dimensions.
