OpenSSL seems to have FUBARed their release process, such that the include/ directory no longer includes anything.  As such I had to update prepare_ssl.py to handle creating include directories for 32 and 64 bit.  This is somewhat wasteful since the only thing really different between the two is opensslconf.h, but this is the simplest approach.

With that update, builds of 2.7 using the old project files in PC/VS9.0 now require Perl to be available to create the makefile.  I don't think this is an undue burden; on the other hand, making prepare_ssl.py handle the requirements of the old build_ssl.py is far more effort than I want to invest.

Steve, would you mind double-checking my work if you get a chance?  I committed in a bit of a hurry at the request of Intel.
