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.

When registering a plugin with `$cacheable=false` the plugin is called
everytime the page is displayed, even if the page comes from the cache.

In contrast to [`{insert}`](#plugins.inserts) the attributes to the
plugins are not cached by default. They can be declared to be cached
with the fourth parameter `$cache_attrs`. `$cache_attrs` is an array of
attribute-names that should be cached, so the plugin-function get value
as it was the time the page was written to cache everytime it is fetched
from the cache.
<?php
$smarty->setCaching(Smarty::CACHING_LIFETIME_CURRENT);
function remaining_seconds($params, $smarty) {
$remain = $params['endtime'] - time();
if($remain >= 0){
return $remain . ' second(s)';
}else{
return 'done';
}
}
$smarty->registerPlugin('function','remaining', 'remaining_seconds', false, array('endtime'));
if (!$smarty->isCached('index.tpl')) {
// fetch $obj from db and assign...
$smarty->assignByRef('obj', $obj);
}
$smarty->display('index.tpl');
?>
where `index.tpl` is:
Time Remaining: {remaining endtime=$obj->endtime}
The number of seconds till the endtime of `$obj` is reached changes on
each display of the page, even if the page is cached. Since the endtime
attribute is cached the object only has to be pulled from the database
when page is written to the cache but not on subsequent requests of the
page.

You can keep parts of a page dynamic (disable caching) with the
