Linux support

[vec2pt]

I made an attempt to compile StarterBot on Linux. Unfortunately I had to make small changes to src to make it work.

1. error: ‘size_t’ does not name a type

The simple solution is to add #include <cstddef> to the ./src/starterbot/Grid.hpp file.

After these two changes, the code compiles without problems (on Linux, unfortunately I have no way to check it on windows). Makefile and instruction can be found in my fork. Remember that you said in one of the videos that you plan to support Linux, I will be happy to pull these changes into your repo. Maybe it's a good idea to create a new branch?
