This commit matters. Really.
THE CRAZY COMMIT (see below)

Final means when you try changing a variable later you know it wasn't
previously expected to change, and thus can evaluate your code to ensure
you don't have later code expecting an unchanged value.

Prepending 'this' allows for much easier reading, knowing what's a field
and what's a local variable.

Calling static fields with the class prepended lets you know it's
definitely a constant in this class and that you're not insane.
