Subject: [PATCH] Windows PuTTYgen docs: remove redundant text.

When I was writing the documentation for the new command-line options,
I wondered why there was an existing section for the corresponding GUI
setting for each option I'd added except strong primes. Now I've found
it: strong primes are discussed in the same section as prime-
generation methods. So I can replace the second explanation with a
cross-reference.
