Literals marked up with _() in templates are translated at compilation time, don't change when locale is switched

[Ramiro Morales]

This issue had been reported in the -dev mailing list a while back: ​https://groups.google.com/d/topic/django-developers/rxjxtwEMAEY/discussion

>>> from django.utils.translation import activate, deactivate
>>> from django.template import Template, Context
>>>
>>> activate('de')
>>> t = Template("{{ _('No') }}")
>>> activate('nl')
>>> t.render(Context({}))
>>> 'Nein' # Should be 'Nee'

Proposed fix changes a call from ugettext() to ugettext_lazy() in handling of the '_(', ')' literals during template variables resolution. Tests included also verify trans and blocktrans tags work, just in case.

(In [15327]) Fixed #15157 -- Modified evaluation of literals surrounded by _(' and ')' in templates to be evaluated at render time instead of at compile time by using ugettext_lazy. Thanks Jonathan S for the report.
