Declare variables locally
- The `allSections` variable was leaking into the global scope, due to a
  typo in the declaration.
- `dataProcessed` can be declared more narrowly within the callback.

to successfully call a function with parameters by setTimeout,
it needs to be a function that will be called by setTimeout internally.

this patch actually enables multiple tries for calling the setState function.

Added JSInput template to Studio and a sop attribute to JSInput. Only if it's set to false, as in JSInput's template, will JSChannel be used to bypass it. In all other cases (attribute not present or set to something else), SOP is enforced. Compatibility with jsVGL is therefore maintained. Multiple JSInput are supported in a vertical. Also, save button now functions. [BLD-523, BLD-556, BLD-568]
