Allow querying a service's name.

Since we can now open a service by its display name it may be
interesting to know what its canonical name is.

Find out with:

    nssm get <displayname> Name

+The Name parameter can only be queried, not set.  It returns the service's
+registry key name.  This may be useful to know if you take advantage of
+the fact that you can substitute the service's display name anywhere where
+the syntax calls for <servicename>.

 The ObjectName parameter requires an additional argument only when setting
 a username.  The additional argument is the password of the user.
