Review of unit test suites

Review of unit test suites
* There's more than ok(), equal() and deepEqual(). Using the others as appropriate.
** Considered: strictEqual(a,b) tests the same as ok(a===b). But the latter doesn't include the values in the report when it fails. So strictEqual saves a lot of time in debugging (especially on TestSwarm where the report is all you have, there "not okay" or "Expected { foo: 500 }, Given: ['bar', '250']" is a big saver.
* Adding an "expect" to every test.
* Applying whitespace conventions and bringing consistency in the use of mw, mediaWiki, $, $j, jQuery. (except in the initial test where the aliases are being checked)
* Added cleanup for added CSSStyleSheet
* Making IPtest more complete (Based on IPTest.php)
