Add support for all atoum's native arguments

This commit adds support for quiet all atoum's native arguments.
I had to disable ```--version``` and ```--help``` as they are already used by Symfony.
I also disabled ```--loop``` as it produce weird errors.

To use the arguments, we need to write them using their long version :

```sh
$ app/console atoum AcmeDemoBundle --no-code-coverage --configurations=my-atoum-config.php
```
