Update tex-memoir{,-doc} to 3.6gpl6.0g.

Changes:
-- fixed typo in trimmarks
-- changed \chapter (and chapter like titles), \section's, \part
   and \book such that a non-zero \parskip no longer interfer
   with the title layout.
-- yet another fix for the reimplemented page notes. Now 'x    x'
   only result in one line break not several.
