ikiwiki/doc/todo/Bestdir_along_with_bestlink_in_IkiWiki.pm.mdwn

This patch adds function bestdir() which returns best directory from the directory structure. This is in addition to the bestlink() function which is there in IkiWiki.pm 

> Um, what is this for? :-) It would probably be a lot easier to review if it
> had documentation, and/or a plugin that used it. --[[smcv]]
