Update Parameterize plugin for QUnit2.x

[bluePlayer]

It was deprecated for QUnit 2.x. I oppened the file in Aptana and modified to work without warnings in JSlint. I also removed async() which does not exist in QUnit 2.x and test() function should be used according to the upgrade guide: http://qunitjs.com/upgrade-guide-2.x/

I also added init() function which accepts array of objects which represent parameters for each test case. It returns this(the "cases" object).

I also added test parameters as text when using createTest() so you see which parameters are sent for each specific test.

@AStepaniuk, do you think you are going to accept this PR? My team is kind of stuck because we need to move to QUnit2.x but we also use qunit-parameterize.

@durandj Hello. I wrote a tutorial on how to use my update of the plugin: http://tunephp.blogspot.mk/2016/11/qunit-parameterize-plugin.html

It works well but I haven't used combinatorial and sequential much so I cannot say these functions are bug free. Yes I have tried them just so I try them, they don't break while executing.
I also haven't need for combinatorial. Sequential is by default. All sets of parameters you give in the init() array argument are executed sequentially. I have also used it with done() https://api.qunitjs.com/QUnit.done/ which is executing tests asynchronously.

Hope this helps.
