06: Created Assembler: hacker

I wrote it in C++11 since I am very rusty in it, just to practice. It's
obvious that a lot of improvements can be done. But I am too tired to work on
it right now :)

To compile: g++ hacker.cpp -std=c++11 -o hacker -Wall

The binary expects one argument, the .asm source file.
Eg: ./hacker Pong.asm

There is no sanity check, or anything like that.
