Improve strings used for <title> and header of directory pages

Our legacy method for creating directory titles involved concatenating the
component name into '% Directory', which did not work well in languages where
a term like 'Groups Directory' would be translated into a single word. In
addition, there was inconistency between the <title> element on directory pages
and the header element used in the page body.

This changeset introduces a 'directory_title' parameter to BP_Core_Component,
so that directories can register a fully localizable string as the title/
header for directories.

To avoid filter name conflicts, the filter names associated with the headers
on group and blog directory pages were changed to _directory_header. See r7942,

See #4726, #4630

Fixes #4631
