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.
