Subject: [PATCH] fixed scope for macros (macros can be imported in a block or outside of a block)

    {% import "macros" as foo %}
    {% from "macros" import foo, bar as bar %}

    {% block foo %}
        {% import "macros" as foofoo %}
        {% from "macros" import foo as foofoo, bar as barbar %}

        {{ foo('something') }}
        {{ bar('something') }}

        {{ foofoo('something') }}
        {{ barbar('something') }}
    {% endblock %}
