Fixed one platform bug

Fixed a platform bug. Top-left platform gap works.
Cleaned things up.

Made "Block" follow java code-style rules and fixed up comments. "Here is where I implemented all of the integers and variables which I use
-  in the rest of the program." was unnecessary. They're instance variables. Of course they'll be used throughout the rest of the program.
Update MainThread.java
