Use the convert_boolean_return attribute in the powershell_script
resource to do the right thing. See the documentation for information
about what that does & why.

http://docs.getchef.com/resource_powershell_script.html

I imagine that this will become the default when :guard_interpreter
becomes :powershell by default for powershell_script.
