The root level .gitignore file already works for all sub-repositories, so they are all actually unnecessary.
This PR leaves only the gitignore at the root of the repo, removing all others.
As discussed previously, this PR moves the Space Shooter Tutorial to the tutorials folder for direct inclusion in the docs. A few things to note, other than basic grammar and formatting, nothing was changed other than migrating the information to the current tutorial format. This should allow the tutorials.flame-engine.org subdomain to be deleted.
Note: Upon moving this tutorial, I discovered it is incomplete and missing the majority of the game.
Also, I realized that I left the android folder and some files that weren't necessary for the platform tutorial and have deleted those.
This adds a platformer tutorial called Ember Quest. I hope I have done a service, because I am tired, lol. I am sure there will be comments. I just want to say, I did my best. I approached this as someone new to Flame, just like I was about 10 months ago. Are there concepts that can be improved, sure. We can always optimize code, but I didn't want any concepts to be super abstract. I had never coded a game before when I began my journey with Flame this year, so things might be a bit simple for experienced game developers, but for myself, I had never even thought about a game loop or animations, etc.
