Minor fix for tornado upload support
Merge pull request #327 from flambert/missing-block-parameter-name

Add missing block parameter name preventing auto-complete to work
fixed AFHTTPClient documentation
Remove unused kAFMultipartFormLineDelimiter.

This constant appears to have been superseded by the introduction of
kAFMultipartFormCRLF later in this source file.  The latter is used
consistently in the multipart-building code, so this first one can go.
Avoid appending empty form data parts.

AFQueryStringComponentsFromKeyAndValue() always returns at least one
component (even if its `value` parameter is `nil`).  If a component
doesn't have any form data, there's no need for us to append an empty,
nameless part to the multipart body.

Additional improvements to consider (which are not mutually exclusive
with this change):

 - Don't run this loop at all when `parameters` is `nil`.
 - Change AFQueryStringComponentsFromKeyAndValue() to return an empty
   iterable when its `value` paramter is `nil`.
