The jquery mainline is lagging on support for responseType:
'arraybuffer', an XHRHTTPRequest Level 2 feature (whatever that means).
We use this responseType to transfer attachments.
I rebased https://github.com/jquery/jquery/pull/1525 on the 2.1.1
release and cut 2.1.1-ajax-nativetransport in my own fork.
Latest protobuf.js requires that we pass in the sign value when making
longs from strings, ex: dcodeIO.Long.fromString(id, true);
However, it does the string->long conversion automatically if its given
a string for a fixed64 field, so we can pass our string ids right in!

Set up grunt with tasks for:
* preen - deletes unused files from bower_components, configured in
bower.json
* concat - concatenates preened bower components, configured
automagically from the preen config
It's worth noting that this setup assumes the order of files within a
package doesn't matter. This is usually true since we often include only
one file from the package.
Moved all test code into /test. Renamed test.js to crypto_test.js.
(Let's try to keep test files topical.) Merged test_views.html and
test.html into a single test/index.html.
Todo: use Grunt to generate test/index.html from index.html and files
found in /test. Also, write more tests.
We now correctly and opportunistically use the webcrypto API if
available, polyfilling if it's not detected. This change also includes a
layer of abstraction over the webcrypto interface so we no longer have
to deal with key-imports or algorithm names all over the place. Since we
no longer support AES-CTR, code outside this file can simply call
`textsecure.subtle.<encrypt|decrypt|sign>(key, data [, iv])`.
TypedArray.prototype.set doesn't handle ArrayBuffers correctly (it
writes all zeros). Instead, wrap each ArrayBuffer in a typed array
for concatenation.
processData (default: true)
Type: Boolean
By default, data passed in to the data option as an object (technically,
anything other than a string) will be processed and transformed into a
query string, fitting to the default content-type
"application/x-www-form-urlencoded". If you want to send a DOMDocument,
or other non-processed data, set this option to false.

Parse attachment ids out of the attachment pointer url and return them
as strings because the copy parsed by JSON suffers a loss of precision.
Convert them to and from the format expected by the protobuf using
facilities from decodeIO.Long.
Sadly, we are not quite compliant with the WC3 webcrypto spec
due to our insistance on passing around key data in plain old
ArrayBuffers.
Also converted whitespace.
DRY up protobuf declarations and move to a slightly briefer naming
convention.
Also dropped some ArrayBuffer -> string conversions as
ProtoBuf.js handles ArrayBuffers just fine, and in fact, more
efficiently than strings.
Finally, dropped the btoa() wrappers, because that incurs an extra
string -> string conversion before the protobuf's internal string ->
array buffer conversion. In lieu of btoa, we can simply pass in the
optional string encoding argument to the protobuf's decode method,
which in these cases should be 'binary'.

All the group messages were being sent to the last recipient in the
list, due to the persistence of `var number` in later loops and async
calls. An easy mistake to make, when you use for instead of each.
