core: removed pyfeed and xe dependencies:

pyfeed and xe where still used only for date format handling, and there is already dateutil which is a dependency of Wokkel.
    Furthermore pyfeed and xe are still not on pypi, causing troubles for installation with pip

 You can automatically install SàT and its dependencies using easy_install or pip. You will however need to install Python's headers (needed to build some packages), WxPython which is available in most Gnu/Linux distributions, PyGObject and developments version of libxml2 and libxslt (to compile lxml python library).
 
-NOTE: pyfeed and xe are mandatory dependencies, they should be on http://pypi.python.org (PYthon Package Index, the official repository for Python projects) and so being automatically installed; but they are not yet there (their author should do it soon), so you have to install them manually until then.
-You can download them respectively on http://home.avvanta.com/%7Esteveha/pyfeed-0.7.4.tar.gz and http://home.avvanta.com/%7Esteveha/xe-0.7.4.tar.gz, then decompress them and do « python setup.py install » on both.
-An other way is to use the (insecure) pip options --process-dependency-links and --allow-all-external when installing sat, options which will soon be (or already are) removed from pip.

 The environment variable SAT_INSTALL customises the installation, it contains flags separated by spaces:
 	- "nopreinstall" skips all preinstallation checks
 	- "autodeb" automatically installs missing packages on Debian-based distributions
 	- "nox" disables installation of X-based packages (WxWidgets), this is useful for servers

 Pyjamas:
 Libervia is built with a Pyjamas (http://pyjs.org), a Google Web Toolkit port for python, including Python to Javascript compiler, and Pyjamas Desktop which allow to execute the same application on the desktop or through a browser. It's really an amazing tool.
 
-Pyfeed and Xe:
-SàT core and Libervia use pyfeed and xe (http://home.avvanta.com/%7Esteveha/pyfeed.html), 2 libraries made Steve R. Hastings really useful to parse/generate xml stuff as atom feeds.

 lxml(http://lxml.de/):
 this powerful and efficient XML parsing module is used sometimes to replace Twisted internal tools: its API is handy, and it have some features like evil content cleaning.
