Automatically create tag pages,

if "tag_autocreate=1" is set in the configuration. The pages will be created in
tagbase, if and only if they do not exist in the srcdir yet. Tag pages will be create from
"autotag.tmpl".

At this stage a second refresh is needed for the tag pages to be rendered.

Add autotag.tmpl template.
