Add kwargs to table init call in SingleTableMixin

Fixes: issue-108
added missing import
support for localize in columns

The reason for cell_l10n.html is backwards compatibility with Django 1.2.
This template is included in the default `table.html` template
and this way we avoid errors of not finding the `l10n` tag library
some clarification
support for localize in Table Meta class

with localize/unlocalize tuples
some documentation about controlling localization
