TNL-256

Student couldn't able to submit his answer in ie9
becuase mathjax was used before its complete loading
thats cuase the problem. Mathjax operations should be
handled synchronously inorder to avoid error.

And whitespace corrections (automatically made by my editor, and I'm too lazy
to remove them)

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.

Clean up fixtures automatically between tests
- Nesting test fixture markup within a DIV allows Jasmine to
  automatically restore the fixture to a clean state between each test
  run.

Fix id attribute collision typo
- This looks like a copy/pasta gone wrong; the two test INPUT elements
  were both declared with the same id, `input_1`.

Remove trailing whitespace

The behavior previously tested here was to check that if a JSInput
element was marked as not processed, re-walking the DOM *should* have
reinitialized it. Unfortunately, this behavior is not supported by the
underlying JSChannel library. In fact, if JSChannel detects an existing
channel with the same origin and scope, it throws an uncaught exception,
leaving the DOM in a "broken" state.

JSInput will prevent duplicates from being added, as long as we don't
manually update the `data-processed` attribute. This behavior is already
being tested.

Select DOM elements with wildcard syntax

- DOM lookups were being done with non-existent literal selectors, so it
  was returning empty lists. As assertions were to be made while
  iterating over the list of elements, nothing was actually being
  verified.

- Common code has been centralized in the setup function. By declaring
  CSS selectors once, we minimize the odds of inadvertently using the
  wrong selector, as happened here.

- Had these tests actually been iterating over a non-empty list, this
  would have thrown undefined exceptions. jQuery.each calls its handler
  with an index and an item/object as the arguments. However, the object
  is a DOM-object, not a jQuery-object.  These tests break, as they had
  assumed the latter.

This test currently fails, meaning that the existing tests weren't
testing what they claimed.

Assertions are made for each element returned by the CSS selectors.
However, the selectors are assumed to be wildcard matches, but are
actually literal selectors. As there are no matched elements, this
causes the assertions to be (silently) checked zero times, without
failure.

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.

codemirror-compressed.js

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]

Removing "logme" from comments.

Affects:
Choicegroups, option inputs, textline, and formula equation inputs

Change the `MathJax.Hub.Queue(initializeRequest)` to a simpler function call
(`initializeRequest.call(this)`). This was failing to give a proper context
to initializeRequest, and `this.value` was turning up as `undefined`.

Also add a fallback if we need to display some code before MathJax finishes
its original typesetting.

I was stubbing out `Queue` in my specs, so the tests had to be changed around
a little.

Named `FormulaEquationInput` (name up for debate)

- Based off ChemEqnIn
- Add FormulaEquationInput in inputtypes.py
- Add a call to a skeleton method for a preview

javascript:

- Queue up some MathJax
- Put some ordering on the AJAX requests: add a parameter when the request was started, when it returns check that it isn't outdated before displaying the preview
- Tests

Note: we moved the `jsinput` tests and DISABLED them, because they were causing the tests to fail.
