If field is rendered by subclass of MultiWidget, set attrs to
    sub-widgets.

    Also accept `Field` argument `attrs` as iterable, which size must
    be same as the number of sub-widgets.

Avoid polluting the global template context

The node context needs to be deepcopied from context. Updates to
`context` variable affect the whole context of the template where `{%
crispy %}` tag is being used.

This fixes #GH-54
Adding support for hiding fields using Field layout object

Field('field_name', type='hidden')

This solves issue #GH-55

When Django calls `BoundField.as_widget`, that one calls `widget.render`
method, which builds the list of attributes calling `build_attrs`. This
one here, gives priority to the field attributes, before to the
attributes passed to the widget.

So we need to play this one different.
