The new features are:

  eg. 'for ($var(k) in $(json(foo.keys)[*]))'

* iteration over $json object values
  eg. 'for ($var(v) in $(json(foo.values)[*]))' or
  'for ($var(v) in $(json(foo)[*]))'

* iteration over $json array values
  eg. 'for ($var(v) in $(json(foo)[*]))'

Closes #1458

  Fix detection of the $json pseudo variable type

This fixes incorrectly thrown parsing errors for the json_link() module
function and also when using $json iterators in foreach statements.
