Lino learns Portuguese
----------------------

Added pt-br to the list of supported locales:

- .po and .mo files contributed by Flavio
- `env.languages` in :file:`fabfile.py`

Demo users in :mod:`lino.ui.fixtures.demo` :

Added a warning "No demo user for language %r." to be 
issued when :setting:`languages` 
contains an unsupported language.

Added a fictive demo user "Ronaldo Rosa" for `pt-br`.

Added `pt-br` as language in :mod:`lino.projects.min1.settings`.

Added this blog entry to the list of tested docs which makes 
it part of the test suite. When working on it I do::

  $ python setup.py test -s tests.BlogTest.test_20130622
  
(EDIT: later I removed the entry again. The following snippets 
are now obsolete and no longer being tested 
and are only for history documentation purposes.)
  
.. first some general stuff  

    >>> import os
    >>> os.environ['DJANGO_SETTINGS_MODULE'] = 'lino.projects.min1.settings'
    >>> from lino.api.shell import *
    >>> from django.test import Client
    >>> client = Client()
    
>>> ses = settings.SITE.login('ronaldo')

>>> ses.set_language('pt-br')

Django silently ignores it when you try to activate an invalid language,
so we explicitely test whether pt-br is activated:

>>> from django.utils import translation
>>> translation.get_language() 
'pt-br'

The following table should render in Portuguese:

>>> ses.show('users.UsersOverview')
================= ================== ==========
 Nome de usuário   Perfil do usuário  Idioma
----------------- ------------------ ----------
 robin             Administrator      en
 ronaldo           Administrator      pt-br
================= ================== ==========
<BLANKLINE>

But it doesn't (the above snippet fails).

And the same table in German? This works:

>>> ses.set_language('de')
>>> ses.show('users.UsersOverview')
============== ================ =========
 Benutzername   Benutzerprofil   Sprache
-------------- ---------------- ---------
 robin          Administrator    en
 ronaldo        Administrator    pt-br
============== ================ =========
<BLANKLINE>

Hm... still meditating on that (no checkin).
