template bug & translation suggestions

[bugmenot]

Hi,

I recently installed PhpDig v.1.8.7 and I found a bug in results:

If you choose a template (ex gaagle), make a query for results, and one of results you click on "limit to" or "this path" for limit results to url or path, the actual template will be changed to default. A rapid fix, add "template_demo=xxxx" to http query in this links, but a more elegant solution is using cookies or php sessions to store the template.

I have a suggestion, in results, strings "Relevance" and "last update" are constants defined in templates, so will appear in english for al localization. It will be good adding them to locale translation system.

Thanks for this cool project and keep the good work!
