dev-python: merge most python2 and python3 recipes.

* adjust recipes depending on these, ie python_dateutil=>dateutil_python.
* switch architectures to any for relevant python recipes.
* bump versions for retext, argh, beautifulsoup, cssselect, dateutil,
docutils, fonttools, html2text, httplib2, lxml, mechanize, mock, paramiko,
pillow, pip, pygments, requests, twisted, urllib3, zope_interface.

+SUMMARY="HTTP library with thread-safe connection pooling, file post, and more"
+DESCRIPTION="- Re-use the same socket connection for multiple requests \
+(HTTPConnectionPool and HTTPSConnectionPool) with optional client-side \
+certificate verification.
+- File posting (encode_multipart_formdata).
+- Built-in redirection and retries (optional).
+- Supports gzip and deflate decoding.
+- Thread-safe and sanity-safe.
+- Works with AppEngine, gevent, and eventlib.
+- Tested on Python 2.6+, Python 3.2+, and PyPy, with 100% unit test coverage.
+- Small and easy to understand codebase perfect for extending and building \
+upon.
+
+For a more comprehensive solution, have a look at \
+Requests <http://python-requests.org/> which is also powered by urllib3"
