2 template features:
- added a {html_head} smarty block - allow any template file to add content just before </head> tag (handy for plugins and allows to move more presentation logic to tpls); the content is usually <style> or <link> which must appear inside html <head> tag
- by config allow some language strings to be replaced during template compilation -> better performance. drawback: changes in the language file will not be propagated until template is recompiled.
