* Processes a POST (if there was one) of the registration form. If there was not a successful registration, then modifies

* was a successful registration, false if there was no registration attempt or an error.
*
* If registration is successful, also sets 'apiKey' key in the 'data' array to the new API key that was created.
*
* @param data - array - an associative array whose keys are the names of the the variables for the template, and whose values should
* be the default values for those fields. This will be modified (overridden) by any of those values which were posted
* to this page.
* @return mixed - boolean true if there was a successful registration, false if there was no registration or a failed attempt. If there was
* an error, that will be added to the 'data' array under the key 'errorString'.
