Pattern Language rewrite (#111)
* Initial parser rewrite effort
Lexer and Token cleanup, Parser started over
* Greatly improved parser syntax
* Reimplemented using declarations and variable placement parsing
* Added back unions and structs
* Added enums as well as mathematical expressions (+, -, *, /, <<, >>, &, |, ^)
* Code style improvement
* Implemented arrays and fixed memory issues
* Fixed more memory issues in parser, reimplemented validator, evaluator and patterns
* Fixed builtin types, arrays and reimplemented strings
* Improved error messages
* Made character a distinct type, used for chars and strings
* Implemented padding, fixed arrays
* Added bitfields
* Added rvalue parsing, no evaluating yet
* Added .idea folder to gitignore
* Fixed build on MacOS
* Added custom implementation of integral concept if not available
* Rebased onto master
* Fixed array variable decl crash
* Added rvalues and dot syntax
* Lower case all pattern language error messages
* Fixed typo in variable name
* Fixed bug where preprocessor would not ignore commented out directives
* Reimplemented pointers
* Fixed rebase issues
