Supply the list element index in the second #each parameter when enumerating #99

This is useful when conditionally formatting the first or last element in a list, or when generating unique identifiers for each element - for example, when formatting HTML tables.

{#each e, i in ['a', 'b', 'c']}
  Element: {e}
  Index: {i}
{#end}

produces:

  Element: a
  Index: 0

  Element: b
  Index: 1

  Element: c
  Index: 2
