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="Stateful programmatic web browsing in Python"
+DESCRIPTION="Stateful programmatic web browsing in Python, after Andy \
+Lester’s Perl module WWW::Mechanize.
+
+- mechanize.Browser and mechanize.UserAgentBase implement \
+the interface of urllib2.OpenerDirector, so any URL can be opened, not \
+just http.
+- mechanize.UserAgentBase offers easy dynamic configuration \
+of user-agent features like protocol, cookie, redirection and \
+robots.txt handling, without having to make a new OpenerDirector \
+each time, e.g. by calling build_opener().
+- Easy HTML form filling.
+- Convenient link parsing and following.
+- Browser history (.back() and .reload() methods).
+- The Referer HTTP header is added properly (optional).
+- Automatic observance of robots.txt.
+- Automatic handling of HTTP-Equiv and Refresh."
