Test Web Services form; Updated to use POST by default for Authentication Requests

The Test Web Services form has been updated as follows:

• The default Format for Web Services Requests is now "JSON"
• You can now specify whether to authenticate (connect) using either a POST (default) or GET request. This applies to all of the following User Types:
• Client
• User
• User (Token)
• Web Administrator

Using a POST requests sends the parameters as part of the request body rather than the URL and is the recommended way of connecting to Web Services. This is only available to JSON formatted requests.
