Subject: use MSXML.DOMDocument instead of InternetExplorer.Application

* spec/ruby/library/win32ole/fixtures/event.xml use MSXML.DOMDocument
  instead of InternetExplorer.Application. InternetExplorer.Application
  is not available on some environments. Thanks to MSP-Greg (Greg L).
* spec/ruby/library/win32ole/win32ole_event/on_event_spec.rb: ditto.
