[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).
