Toon Shader v4 for Blender EEVEE

This is the 4th version of my personal Toon Shader.
Support edition comes with the matcap source files if you want to change or make new ones, but it's mostly for those who want to support me and future improvements.

V4.1 Changes:

- Added an extra Shadow Softness option, you can control it with the Finetune and Shadow 1/2 settings.

- Changed old Shadow Softness to "Shadow Softness 2".

- Fixed Specular not being able to be set to full softness.

- Some minor improvements to the node tree.
