puzzles: remove redundant help content

It used to be that each puzzle had a complete copy of the entire
puzzles manual and the "quick help" text for every single puzzle. This
was obviously a waste, so now each puzzle only has the sections of the
manual that apply to it, saving about 100KB or so per puzzle. This
also has the added benefit of shrinking binary size enough to allow
full help support on the c200v2, which has been enabled.
