Change Hazel license from Apache license 2.0 to MIT.

[blueice08]

I was wondering why not use the MIT license instead of the Apache License 2.0? I've been following along all the game engine series episodes as a learning resource and at some point I want to use it as a base for my own game engine, the thing is that with the apache license you have to keep track of every single change you make to the code and state all that changes in a file or in the license which seems kind of impractical, specially for a game engine since you have to constantly change things. Wouldn't it just be better to change the license to MIT?
