Add dark mode to documentation

[berk-efe]

There were following modules missing;

• pillow
• python-tkdnd

Also i wanted to add dark mode. There were no change on the initial theme. I have found a dark mode for the exact same theme!

sphinx-rtd-dark-mode

And added
docs/_build
to .gitignore since we do not want builds on repo.

I really liked your project btw. 😃

Thank you for taking interest in the project. These two modules (pillow and python-tkdnd) are not required for the documentation build process and should not be included here.

My bad, i saw missing dependency errors after running make html, so i thought they were a necessity

I will change it now.

I see. Ideally you should have installed the main dependencies of the project which are specified in the root requirements.txt for autodoc to work.

I have forgot to commit .gitignore so i did that too.

LGTM.
