added a way to set planned tests

In order to check that every planned test has actually
been executed, a new optional `planned` parameter has been
added to `Tester.done()`:

```js
casper.test.assert(true);
casper.test.assert(true);
casper.test.assert(true);
casper.test.done(4);
```

Will trigger a failure:

```
fail: 4 tests planned, 3 tests executed.
```

+#### Specification of planned tests ####

+In order to check that every planned test has actuall been executed, a new optional `planned` parameter has been added to `Tester.done()`:
+
+```js
+casper.test.assert(true);

+
+Will trigger a failure:

+```
+fail: 4 tests planned, 3 tests executed.
+```
+
+That's especially useful in case a given test script is abruptly interrupted leaving you with no obvious way to know it and an erroneous success status.
+
+The whole [CapserJS test suite](https://github.com/n1k0/casperjs/tree/master/tests/) has been migrated to use this new feature.

 ### Bugfixes & enhancements
 
 - fixed [#281](https://github.com/n1k0/casperjs/issues/281) - `Casper.evaluate()` should take an array as context not object
