html_options

Hey list,

User Sweetums recently asked on the IRC channel about a weird problem in 
html_options. See this code snipet:

--- template ---
{html_options name=foo options=$myOptions selected=$mySelect}

--- .php ---
$smarty->assign('myOptions', array(true => 'test', false => 'foo'));
$smarty->assign('mySelect', false);
$smarty->display('test.tpl');

This will not select foo as default option because the boolean in select 
is casted to a string (resulting in an empty string) but in options the 
boolean is casted to an int (resulting in 0). This patch should fix it up:
