add optional postamble required by .NET multipart requests
use Request.abort() to abort the request when the request has timed-out

This change will affect the behavior of request that has timed-out.
Now when a user is listening for the error event on a request and that request times-out,
The error handler will only be called once. The error given to the callback will be the timeout error.

[PATCH v4] Clarify gzip handling in the README

Make it more explicit in the documentation about which data is
unmodified and which is automatically decoded when using the `gzip`
option (data passed through request is decoded while the response object
is unmodified and thus its data may be compressed).  Add an example to
README.md to clarify.

Changes since v3:
 - Rebased against current master.

Changes since v2:
 - Make note of gzip example in examples section to alleviate confusion.

Changes since v1:
 - Reworded to refer to streams generically rather than the 'data' event
   specifically.
