Title: 0.9.9 64 bit support, upgrade 32 bit to 0.9.9, and RbConfig for CPU detection 

I added the 64 bit binary using 0.9.9 support, and brought the 32 bit to the same version. I used 0.9.9 instead of the latest 0.11.0_rc1 due to an extra library dependency, which I filed at http://code.google.com/p/wkhtmltopdf/issues/detail?id=968

I switched the CPU detection to use RbConfig, as RUBY_PLATFORM has been shown to be inconsistent between different ruby implementations.
