Add module and test-name information to callbacks

[vivin]

I think it would be useful to add the module and test-name information to callbacks.:

• QUnit.log currently only reports the following information actual, expected, message, result, and source. I think it would be useful to add module and testName to this.
• QUnit.moduleDone and QUnit.moduleStart don't report any information regarding the actual module that has started or finished. I think it would be useful to pass that information to the callback.
• QUnit.testDone and QUnit.testStart don't report any information regarding the actual test that has started or stopped. I think it would be useful to pass that information to the callback.

I apologize if this change has already been made, or if this information can be retrieved some other way.
