The windows installation instructions were very out of date. Substantial
update to the text. Remove a lot of historical stuff that isn't relevant
any more, and merge the win64 and win32 instructions into one file.

This change resolves a number of problems and obviates multiple kludges.
A new feature is that you can now say "AES256" or "AES128" (not just
"AES", which enables both).

In some cases the ciphersuite list generated from a given string is
affected by this change.  I hope this is just in those cases where the
previous behaviour did not make sense.

(noted by Jonathan Louie <jlouie@recourse.com>).

0.9.7 now lives in the branch OpenSSL_0_9_7-stable.
