Enhancement: Couple o' GitHub changes

[regulad]

Please check for duplicates or similar issues before creating this issue.

What is your suggestion, and why should it be implemented?

Here are a couple suggestions that I would make a PR to propose but can't, because, well, GitHub! Most of these are pretty small and don't matter in the grand scheme of things but still are best practice and should be used.

1. Add a description & link to the website.
   • Just make the description something basic like "Gettin freaky on a Friday night y'all"
   • Link to the website with https, not a lot to that on
2. Add some dang tags!
   • newgrounds, haxe, haxeflixel, etc., all help with SEO and just make everything look a lot nicer
3. Separate LICENSE for assets and code
   • Since this one repo has everyhing, (flash animation files, exported art, music, song data, source code, etc.), there really should be two licenses specified since atm everything falls under the Apache-2.0 license and that isn't really the best for assets.
   • One file named ASSET_LICENSE and one named CODE_LICENSE is best practice.
4. Create Wiki
   • Move the CHANGELOG.md and the Modding.md files to their own page on the wiki too, this makes information much easier to access for people who might not know how to navigate a repo.
5. Move the Github-Pages site to it's own branch

sorry for all these issues and prs i just have a lot of ideas to help the project even though i dont know haxe lol
