Filesystem templates should have programming right by default

See http://markmail.org/message/6w45xmgq62gea2gp

Right now (and since forever) the default behavior for templates is to be executed with the right of the current document content author (it's not really explicit, it's just how PR works when there is no sdoc). This means that unless you explicitly indicate an author for your template (possible since 7.x) you don't really have any idea which right it's going to have at runtime. It also make harder to properly execute templates outside of main rendering thread where the "current document" often don't really make much sense.
