First import of `ghostdriver.qrc` & related files.

Embedding GhostDriver into PhantomJS(!!!)

Finally. After so much work, this is finally a reality.
To launch PhantomJS in "Remote WebDriver mode":

```bash
$ phantomjs --webdriver=OPTIONAL_IP:OPTIONAL_PORT
```

Also, GhostDriver brings along support for Selenium Grid: now PhantomJS can register itself to a Selenium Grid HUB.
Just launch it in Webdriver Mode with the following extra options:
```bash
$ phantomjs --webdriver=OPTIONAL_IP:OPTIONAL_PORT --webdriver-selenium-grid-hub=http://url.to.selenium.grid.hub:port
```

Enable multiple files to be uploaded to a file input

Obviously, the input must have the multiple attribute for this to work.

The API is:

    page.uploadFile('#file_input', ['file1', file2'])

I haven't implemented support for multiple files in the page.filePicker
API because I couldn't work out how to get a return value of an array
of strings through the JS/C++ bridge.

Fix memory leak on linux

We were previously adding the certificates on each instantiation of
NetworkAccessManager, causing memory consumption to grow unbounded.

I have also removed the Qt version check. It's unnecessary as we only
build against a fixed Qt version.

Upgrade to Qt 4.8.4

Guess the DOM has changed a little. No more class .address but an (incorrectly used) <address> tag instead.
