Fix macros with more than 2 arguments

Thanks to the pull request from @gormster, the preprocessor now properly handles macros with arbitrary numbers of arguments.

More big updates coming soon, including @jgOhYeah's table-sertxd, and an option to use the online compiler!

Added all the ppp_* substitutions

In addition to all the features of the 1.2.0 release (which added #IF, #IFDEF, #IFNDEF, #ELSE, #ELSEIF, #ELSEIFDEF, #ELSEIFNDEF, #ENDIF, #UNDEF, and #ERROR), 1.3.0 adds support for the official preprocessor substitutions, so now you can insert the file path and date and/or time into your file whenever desired, good to enable automagic setting of the latest update timestamp in your code!

More preprocessor directives added

Thanks again to @jgOhYeah for the continued contributions, this release now supports
#IF, #IFDEF, #IFNDEF, #ELSE, #ELSEIF, #ELSEIFDEF, #ELSEIFNDEF. #ENDIF, #UNDEF, #ERROR in addition to the already supported #INCLUDE and #DEFINE.
