FLUID-4850: First implementation of basic testing grades
FLUID-4850: First barely working version of sequence tests - currently awful hack for chaining tests, and no proper teardown
FLUID-4850: Working version including -
 - Helpful driver function to chain together test execution
 - "markupFixture" property for environment-directed markup setup/teardown
 - implementation of "jqueryTrigger" executor sequence record type
 - Dedicated diagnostics in qunit UI showing sequence position both when running and concluded sequence
 - Test of a longer 4-element sequence showing more alternation (more required)
FLUID-4850: Working version with changeEvent binding, new "makeListener" support, fix for failure when removing non-present exact listener
FLUID-4869: Fix and test case for failure to unsubscribe ChangeEvent listeners
FLUID-4850: Implementation complete with all planned fixture types - now includes jQueryBind. Code tidyup and a little linting.
FLUID-4850: Renaming of property "args" to "makerArgs" due to conflict, and more tidying
FLUID-4871: Improvement of ProgressiveEnhancement to detect browser environment - fixes to node includes, linting of IoCTestUtils and refactoring to use new ProgressiveEnhancement tag - turned off framework merge tracing by default - improved error message in listener record
