Adding a license to the project

[Arash-san]

I implemented a GUI, some new features, and various fixes to this project for myself some time ago as a personal project. However, I think I can't publish it anywhere since the project has no license, according to GitHub's licensing help page.

My only intention is to publish my version of this amazing repo as an open-source project. Should I fork it and put the changes there? Or am I allowed to create a new repo and give credit to this project in the description?

@Arash-san Feel free to do anything you want with this software. I'll put it on my TODO to add a "do anything you want"-license to this repo.
