README for newbies

[tjkierzkowski]

Hello! I learned about this project through a reddit post and couldn't help but try it out. I know it's like super alpha right now but I wanted to contribute a better readme to help others interested in building/running the project. I only have the prerequisites done and still have to work on the build section. I didn't get to fix the build section just yet because I'm still hacking away at getting it to run via cargo run.

Thanks again for your awesome contribution!

This is neat, but we're using SDL2.
It may be a good idea to switch to GLFW. Thoughts, @bvssvni?

About getting cargo run to work, all you need is to make the argument to AssetStore::from_folder relative to target (../bin/assets in this case).
I already did this in my minecraft branch, and I'm no longer using the Makefile.
Sorry for taking so long to merge that, btw.

It does not matter whether it's SDL2 or GLFW. Perhaps we should have a flag and set it to SDL2 by default?

Here is a link of how to deal with SDL2 problems: PistonDevelopers/rust-empty#175
