* - submitSuccess
* A function that will be called if the report is submitted
* successfully with two parameters: the id that was passed
* to this function, and an object containing the key/value
* data returned from the server in its properties.
* - submitError
* A function that will be called with one parameter if the
* report fails to submit: the id that was passed to this
* function.
* - noThrottle
* If true, this crash report should be submitted with
* an extra parameter of "Throttleable=0" indicating that
* it should be processed right away. This should be set
* when the report is being submitted and the user expects
* to see the results immediately. Defaults to false.
*
* @return true if the submission began successfully, or false if
* it failed for some reason. (If the dump file does not
* exist, for example.)
