Added tools folder with win32 binaries
Added flex/byacc generated files to ignore list.
Moved byacc/flex binaries to new tools/win32 location.
Started implementing namespaces to facilitate project refactoring (rpgtoolkit::rpgcode, rpgtoolkit::rpgcode::functions).
Refactored source code as necessary to work with namespace additions.
Added byacc/flex file generation as pre-build dependencies (cmake)
