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="Hyperfast and lightweight templating for the Python platform"
+DESCRIPTION="Mako is a template library written in Python. It provides a \
+familiar, non-XML syntax which compiles into Python modules for maximum \
+performance. Mako's syntax and API borrows from the best ideas of many \
+others, including Django and Jinja2 templates, Cheetah, Myghty, and Genshi.
+
+Conceptually, Mako is an embedded Python (i.e. Python Server Page) language, \
+which refines the familiar ideas of componentized layout and inheritance to \
+produce one of the most straightforward and flexible models available, while \
+also maintaining close ties to Python calling and scoping semantics."
