Indexed values are now 1 based. This makes it consistent with the size property
when using a range:

   {% for i in (1..names.size) %}
     {{ names[i] }}
   {% endfor %}

Also, since the forloop.Index is 1 based (while Index0 is 0 based), it just
seems more consistent that array indexing should be 1 based.

I think my mom would expect indexes to be 1 based.
