Alien::Base 0.005, static libs, support for windows.

Working with RC for Alien::Base 0.005 I was able to get Alien::LibXML to install on Windows with these commits.  The RC an be found here:

This version will also likely be more reliable on non windows platforms since it uses static libraries when linking XS modules.
