WIP - Removed dependency upon Nokogiri

Replaced usages of Nokogiri with Rexml. While slower, its not noticable since the cost is really the remote WinRM calls anyway.
Add zero exit code test case
Finished TODOs for removing Nokogiri

Removed TODOs which we're not doing
Added write_stdin method and improved message logging
Added rwinrm tool for running an interactive winrm shell on a remote windows box
Merge branch 'pr/57' into winrm-1.3
Moved auth_timeout_spec to new spec location
Updated maintainer/contributor list
Added custom winrm output matchers
Cmd spec uses new output matchers
Added more powershell script tests
