Every header file is now in the includes folder: easier to find, and easier to
For example: we don't need to include some shit like that:
"../../includes/local.h" with aweful relative paths
By the way, local.h wasn't explicit at all, so lot of code has moved to a more
explicit file: Token.[h|cpp] and so on...
I STRONGLY RECOMMAND READING THE LOGS FOR THIS COMMIT!
