man/Makefile.am: add a way to generate "book" out of man pages

Now, this command should create a "book" out of all the man pages:

	cd man && make manual.pdf

Scripts were taked from my old ASPseek project and modified a bit.
Therefore, I do not understand some details, but at least it works.

While at it, also
 - reorganize the list of man pages to better fit the book
 - add targets to generate PDF and PS files out of each man page
 - add 'pdfs' target to generate all possible PDF files
