GS5.2 Ch3 Styles and templates draft

Hi

I have uploaded GS5.2 Ch3 Styles and templates.

Major changes are in the Templates section since the dialog has been
completely rewritten and is now more consistent.

I left out for other times the experimental (and interesting) feature of
"document design" since it misses a bit of a finishing touch. If you
judge it worth to start writing about it right now, I can add a couple
of pages about that are ready.

regards
