This change provides a basic infrastructure for writing browser test in JavaScript, which has several advantages.

1. The JavaScript lives in a separate file instead of inline strings in the C++, which is much more readable.  Since it is not part of the browserTest executable, you can modify it on the fly without re-linking (which takes 70s on a Engineering desktop), that makes development faster.
2. Instead of using sleeps to determine whether an action has happened, we can hook specific events in JavaScript.  This allow more reliable tests that run in a more timely manner.

Overview:
- The infrastructure lives in two file: 
browserTest.js provides basically functionality for reporting results back to the C++ layer
remote_desktop_browserTest provides basic functionality for loading/injecting JavaScript and executing the tests.

- To define a browserTest, create a class under the browserTest namespace with a run method.
browserTest.Foo_Test = function () {}
browserTest.Foo_Test.prototype.run = function () { ... }

- You can then call the following from C++
RunJavaScriptTest(web_content, "Foo_Test", "{ field1: 'data'}"
