Pattern Language rewrite (#111)

Browse Source 
* 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
