Takes a format string (char const*) and a list of tokens (Str) and returns a Str of the formatted string.
Tokens are provided in '<'identifier'>' format where '<' '>' are just angle brackets (you can change it in token_fmt_va)
---------------------------------------------------------
	Example - A string with:
		typedef <type> <name> <name>;
	Will have a token_fmt arguments populated with:
		"type", str_for_type,
		"name", str_for_name,
	and:
		stringize( typedef <type> <name> <name>; )
-----------------------------------------------------------
So the full call for this example would be:
	token_fmt(
		"type", str_for_type
	,	"name", str_for_name
	,	stringize(
		typedef <type> <name> <name>
	));
!----------------------------------------------------------
! Note: token_fmt_va is whitespace sensitive for the tokens.
! This can be alleviated by skipping whitespace between brackets but it was choosen to not have that implementation by default.
