Updated ruby bluetooth bindings based on ruby-bluetooth
(https://rubyforge.org/projects/ruby-bluetooth/)

The above link will only run/compile with ruby 1.8.7. The source hasn't
been touched since mid-2006.

I have currently updated bluetooth_linux to run on 1.9.3. I updated the
headers in macosx and win32 but have not even tried to compile them
since I have neither a mac nor a win32 dev env.
