[PD] import vs namespace

This is only the case on 0.40 and newer. [import] on 0.39 loads into
the global namespace. This stuff is currently alpha and not
complete, so it is not very clear. I think for the manual, the best
bet for Pd-extended is to use the [library/objectclass] format for
objectclasses that aren't loaded by default. That has been supported
by every version of Pd for a long time now (as long as you install
the libraries that way).
