APIKey replaces SessionID

[Todd Gould]

Starting with v3.1.113 - 3/11/2014, you no longer should use Login() to create a SessionID and Logout() to end your session.

Now when a new User is created, an APIKey is generated which can be substituted for the SessionID in all API calls for that user.

To expire that APIKey and create a new one, use the GenerateAPIKey() API.

Keep your APIKeys safe as they have all access to ECGridOS for that user.
