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="Interfaces for Python"
+DESCRIPTION="
+This package provides an implementation of 'object interfaces' for Python. \
+Interfaces are a mechanism for labeling objects as conforming to a given \
+API or contract. So, this package can be considered as implementation of the \
+Design By Contract methodology support in Python.
