Export Wizard values to JavaScript macro

Registers a new function "value('name')", available to the wizard json
files, which returns the value of the variable "name" as a JavaScript
object. So, variables with a string value are actual JavaScript strings,
booleans are booleans, lists are lists, and dictionaries are
dictionaries.

The patch also makes it actually possible to assign JSON lists and
dictionaries to values.

This removes some hacks involving creating complex JavaScript objects
through string substitution.
