Added Po.it support, optimized, cleaned and formatted code

I implemented Po.st support since its the only shorterner I use, I went through and added final modifiers to anything and all things actually final. Just for the sake of functionality and so no one will misinterpret or misuse the thought process which resulted in your code. 

Invalid static modifiers were removed because of redundancy. 

Code was formatted with jalopy
