New theme: Vibrant Ink

[Xeverous]

I propose to add this theme to the list. I made it based on colors from various other (non-IDE) tools that had the theme "Vibrant Ink". Because I edited only C++ highlighting rules, the remaining styles were copied from Modnokai (which is the most similar dark theme).

If I were you, I'd think of creating a pull request. It's much easier for the repo maintainer.
It would also give you the opportunity of making an image for your theme to help others out ;)

The images look very consistent, I guess the maintainer has an example project/code to launch it. I recently changed the project within my company and no longer have a setup with Qt tools installed. A PR is fine though. @ihonen any opinion?
