Added path to Turkish translation

This is awesome!

Instead of linking to an external fork we should add README_TR.md and CONTRIBUTING_TR.md to the main flixel repo and link to those pages in the english versions. I'm also not sure that we should translate the license unless it can be verified by a real lawyer who speaks Turkish, also I assume MIT License is universally understood

That means i need to repull request with your suggestions?

[neondev27]

I did changes you said @Geokureli.

[Geokureli]

1. some formatting issues
2. link to haxeflixel pages
3. move CONTRIBUTING_TR.md to .github/
4. I think CONTRIBUTING.md should have a link to turkish and CONTRIBUTING_TR.md should have a link to english as well

[neondev27]

It is final look of the things. I wish it helped, @Geokureli
