/**
 * Register ajax transports for blob send/recieve and array buffer send/receive via XMLHttpRequest Level 2
 * within the comfortable framework of the jquery ajax request, with full support for promises.
 *
 * Notice the +* in the dataType string? The + indicates we want this transport to be prepended to the list
 * of potential transports (so it gets first dibs if the request passes the conditions within to provide the
 * ajax transport, preventing the standard transport from hogging the request), and the * indicates that
 * potentially any request with any dataType might want to use the transports provided herein.
 *
 * Remember to specify 'processData:false' in the ajax options when attempting to send a blob or arraybuffer -
