Ajax transports to allow the sending/receiving of blobs and array buffers via the familiar jquery ajax function.To send, set data to the blob or arraybuffer to be sent, and add 'processData:false' to the ajax options.To receive, specify the 'dataType' as blob or arraybuffer in the ajax options.
(function($){
/**
* 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.
