Hello,

I got a minor issue with the bbcode parser:
As far as I could see, there is no inheritance for flags, so the following code fails:

Reproduce code:
---------------
<?php

$tags['noparse'] = array(	
	'type'		=> BBCODE_TYPE_NOARG,
	'open_tag'	=> '',
	'close_tag'	=> '',
	'childs'	=> '',
	);
$tags['nosmilies'] = array(	
	'type'		=> BBCODE_TYPE_NOARG,
	'flags'		=> BBCODE_FLAGS_SMILEYS_OFF,
	'open_tag'	=> '',
	'close_tag'	=> '',
	);

$bbcode = bbcode_create($tags);

bbcode_add_smiley($bbcode, ':)', '<img src="/smilies/icon_e_smile.gif" />');

echo bbcode_parse($bbcode, '[nosmilies][noparse]:)[/noparse][/nosmilies]');

?>


Expected result:
----------------
:)

Actual result:
--------------
<img src="/smilies/icon_e_smile.gif" />
