Added check for test case creation when Cross-site scripting security enabled

Test case creation was failing. Investigation showed that when the "Cross-Site Request Forgery" security setting was enabled, the CSRF token and Browser fingerprint were not included in AJAX calls, and the Ruleinskey was not getting passed. This has been resolved by adding a check to evaluate whether security measures are included or not when making a server call from AJAX, and including the tokens required when appropriate.
