Description

The template system's for loop currently doesn't work with a generator because the length of the iterable is required for the variables forloop.revcounter, forloop.revcounter0 and forloop.last.

This patch simply checks for a len attribute on the iterable. If it doesn't exist, a list is created from the iterable and used in its place.
