Rewrote evaluator

* I deleted most of the previous evaluation function once I figured out that state management was unnecessary. It is much more elegant now
* Generators and macros can now return failure. This is especially important for macros so that the macro validation and recursive evaluation doesn't occur needlessly
* Tokenizer no longer removes escape characters. This is so whatever string the tokenizer reads can be output as a string constant to C/C++ without any issues, and exactly as the user input
