templatefilters: rename commonprefix to commondir

Two reasons:

  * It makes it clearer that it's not a generic common string
    prefix (e.g. commonprefix(["bar", "baz"]) is not "ba", but "")

  * If we ever want a filter for generic common string prefix,
    then the name is now available for that.

"commondir" does not describe the prefix-ness, however. I'm happy to
rename it "commondirprefix" or "commonprefixdir" if others prefer.
