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="An event-driven networking engine written in Python"
+DESCRIPTION="Twisted is an event-based framework for internet applications.
+It includes modules for many different purposes, including:
+
+- twisted.application: A "Service" system that allows you to organize your \
+application in hierarchies with well-defined startup and dependency semantics.
+- twisted.cred: A general credentials and authentication system that \
+facilitates pluggable authentication backends.
+- twisted.enterprise: Asynchronous database access, compatible with any \
+Python DBAPI2.0 modules.
+- twisted.internet: Low-level asynchronous networking APIs that allow you \
+to define your own protocols that run over certain transports.
+- twisted.manhole: A tool for remote debugging of your services which gives \
+you a Python interactive interpreter.
+- twisted.protocols: Basic protocol implementations and helpers for your own \
+protocol implementations.
+- twisted.python: A large set of utilities for Python tricks, reflection, \
+text processing, and anything else.
+- twisted.spread: A secure, fast remote object system.
+- twisted.trial: A unit testing framework that integrates well with \
+Twisted-based code."
