implements {{native name}}; entry point from a module

<args_t> is a table of parameter name/value pairs.  Parameters that are supported are:
	args_t[1] - IETF language tag (required)
	args_t[2] - the native name (required)
	args_t.italic - accepts string values 'no' or 'off'; {{lang}} expects 'no' so 'off' must be translated
	args_t.italics - alias of |italic=
	args_t.paren - accepts 'omit', 'off', or 'no'
	args_t.icon - alias of paren
	args_t.nbsp - accepts 'omit' or 'no'
	args_t.parensize - 
	args_t.fontsize - deprecated alias of |parensize=
	args_t.nolink - any value inhibits wikilinking of language name

this function calls these functions in Module:lang:

	add support for romanization and transliteration?
	add support for postfix so that 'mis' can render something like this:
		{{native|name|mis|Chotilapacquen|parent=omit|postfix=&#32;([[Coahuiltecan languages|Coahuiltecan]])}}
			Chotilapacquen (Coahuiltecan)

<args_t> is a table of parameter name/value pairs.  Supports enumerated forms of the {{native name}} parameters:

	args_t.namen - the native name (|name1= required)
	args_t.italicn - accepts string values 'no' or 'off'

	args_t.parenn - accepts 'omit', 'off', or 'no'
