FLUID-4886: Rationalised jqUnit testing system
FLUID-4886: Updating to latest version of qunit trunk in order to resolve cross-context "equiv" issues in GPII/node - we now use the new qunit "propEqual" method for comparing deep equality as more in keeping with our framework-wide opinions on state-equivalence - see https://github.com/jquery/qunit/issues/279 for discussion on this. Updates to fluid.js node driver to fix error with global namespace pollution as well as exposing globally useful method fluid.loadInContext for loading non-require-aware framework-style files. We also improve the fidelity of the node context object by adding setTimeout and a self-linking "window" property.
FLUID-4886: Rationalised tooltip "destroy" as test teardown as per review suggestion
FLUID-4886: Corrected TableOfContents test to avoid stack overflow issue within QUnit when cloning arrays containing DOM nodes for operating propEqual algorithm - converted remaining tests to jqUnit style
FLUID-4886: Various fixes for IE8 issues - stray comma in FluidJSTests, window delete in jqUnit, and actual bug in fluidRenderer! Stray 3rd argument supplied to $.inArray only effective on old runtimes without native indexOf
