Raw params data send

[nwlunatic]

Sometimes it's necessary to have ability to send raw parameters with get request. (especially in testing)

By default there going to be no changes, except fix:
for parameters that were going in url, like, http://h.wrttn.me?key=value, key and value weren't encoded
but now they are, look in tests.

For send a raw request, without url encoding, just need to pass a encode_url=True arg to Request.

Unfortunately this message generated by pycurl/libcurl and tests in travis is failed: https://travis-ci.org/Lispython/human_curl/jobs/19965736#L301

$ curl fwbefrubfbrfybghbfb4gbyvrv.com curl: (6) Couldn't resolve host 'fwbefrubfbrfybghbfb4gbyvrv.com'
or you have another behaviour?

Sorry for comments, I've fixuped commits to prettify pull request.

To answer your questions:

• fixed {} to {0} for python2.6
• fixed "Could not resolve host: {0}" to "Couldn't resolve host '{0}'"

Things about libcurl:

from travis build log:

$ pip install -U pycurl2
Downloading/unpacking pycurl2
  Downloading pycurl2-7.20.0.tar.gz (133kB): 133kB downloaded
  Running setup.py (path:/home/travis/virtualenv/python2.6/build/pycurl2/setup.py) egg_info for package pycurl2
  Using curl-config (libcurl 7.22.0)

while on my machine (ubuntu 13.10) build log says:

venv/bin/pip install -U pycurl2
Downloading/unpacking pycurl2
  Downloading pycurl2-7.20.0.tar.gz (133kB): 133kB downloaded
  Running setup.py egg_info for package pycurl2
    Using curl-config (libcurl 7.32.0)

so I have a

$ curl jgkasdocdofvjsdpoap.com
curl: (6) Could not resolve host: jgkasdocdofvjsdpoap.com

and that the difference between libcurl 7.22.0 and libcurl 7.32.0

Thanks.

I think we can format resolve error string depend of pycurl2.version_info()
