WIX installer stores WinLogon event handler under wrong registry value

WIX installer stores WinLogon event handler under wrong registry value

	The WinLogon event handler in prior versions of the Wix installer
	has been installing the event handler under the registry value "KFWLogon"
	which happens to be the name that "OpenAFS" also uses for its Kerberos
	logon events.   The KFW NSIS installer has used "MIT_KFW" in order to
	avoid the conflict.  The Wix installer is being corrected to match.

	When there is a name collision, only one of the event handlers gets
	installed.  As a result, Kerberos FILE ccaches get created with SYSTEM
	only ACLs and are never destroyed.  This is the same problem that
	happens on Windows Vista when integrated logon is used because the
	event handler hooks do not exist.
