Simon Wisselink cdf1ed2a50 Simplified the (no)caching architecture by:
- removing support for $cache_attrs for registered plugins,
- removing the undocumented {make_nocache} tag and the deprecated {insert} tag and associated code
- removing support for a compile_id property on include tags.

Fixes a bug in extends: resources by propagating the nocache-hashes between a master template and it's subtemplates in \Smarty\Template::_subTemplateRender. This might need further improvement.

templateExists()
checks whether the specified template exists
Description
===========
bool
templateExists
string
template
It can accept either a path to the template on the filesystem or a
resource string specifying the template.
This example uses `$_GET['page']` to
[`{include}`](#language.function.include) a content template. If the
template does not exist then an error page is displayed instead. First
the `page_container.tpl`
<html>
<head><title>{$title}</title></head>
<body>
{include file='page_top.tpl'}
{* include middle content page *}
{include file=$content_template}
{include file='page_footer.tpl'}
</body>
And the php script
<?php
// set the filename eg index.inc.tpl
$mid_template = $_GET['page'].'.inc.tpl';
if( !$smarty->templateExists($mid_template) ){
$mid_template = 'page_not_found.tpl';
}
$smarty->assign('content_template', $mid_template);
$smarty->display('page_container.tpl');
?>

and [`{include}`](#language.function.include)
