IIS: Creates IIS_VERSION definition

This definition is currently used in two different circumstances: Report with
accuracy that the server is an IIS  (status call), and also show the amount of
loaded remote rules on the windows logs. Different from Apache which loads the
rules twice, IIS just do it once.
