c9f2865c83 core: Get rid of duplicate filtering as a scheduler builtin feature. closes #49. 
Implements a DuplicatesFilterMiddleware as spidermiddleware, a wraper
using a minimal defined API of a filtering class configurable by
settings.

Enabling this middleware doesn't gives us same functionality compared to
scheduler duplicate filter builtin, but it filter the most important
source for duplicate requests, the spiders.

What requests aren't filtered by new middleware? The ones originated
from any part of scrapy outside of spiders, like S3 images requests or
any other request manually schedule using ``scrapyengine.schedule()``
method.

Previously, we usually added dont_filter=True to requests created
outside of spiders to avoid collisions downloading same pages than
spider. Now, this is not required anymore because new middleware filters
just the spider generated requests.

There is a caveat, as usual downloadmiddlewares can returns a Request
object at any point of the chain, and that request is scheduled and
downloaded as usual too. One of the downloadmiddlewares using this
feature is RedirectMiddleware that counts on scheduler filtering builtin
to avoid redirection loops. I think we can implement a request time to
live decreasing counter and add it to request's ``meta`` attribute with
a default value if not present, and decrement each time the request is
redirected.

8fdf06ed08 Avoid sending Content-Length header when body is an empty string. 
Some sites can't handle "Content-Length: 0" header, but twisted
HTTPClientFactory adds Content-Length header unless body is None.

scrapy enforces request.body usage as string, using None is not
possible.
