Break, continue and loops' labels

ilyapuchka commented 6 years ago

This PR adds break and continue tags for loops. They can be labeled, like in Swift, or not.

{% for item in items %}
  {{ item }}{% if condition %}{% break %}{% endif %}
{% endfor %}

Labeled loops:

{% outer: for item in items %}
  {% for key in keys %}
    {{ item.key }}{% if condition %}{% break outer %}{% endif %}
  {% endfor %}
{% endfor %}

Also with labels it's now possible to access outer loop context from inner loop:

{% outer: for item in items %}
  {% for key in keys %}
   {{ forloop.counter }}-{{ forloop.outer.counter }}
  {% endfor %}
{% endfor %}

Before I forget: This PR should document the changes in the docs.

Is it something we still want to have or it can be closed?
