Add Github tags to the repository to make it easier to find

[tassa-yoniso-manasi-karoto]

Thank you for making this great project. I think many people may find it useful but it is a bit hard to find.

It would make it easier for people to hear about it by adding thematic tags like this:

Currently the readme says the project is under GNU AGPL 3.0 License but the licensed provided in the repo is the GPL3. I think you can add the license from github too so that it is automatically displayed to the side underneath the tag.

Thanks!
