Support for xml output to stdout

[jmglsn]

I needed to get the output of phpcpd direct on sdtout. I'm currently expanding my netbeans plugin to support phpcpd too.
So I added --xlm-out to pass through phpcpd-xml direct to cmd.

Just log to php://stdout and use --quiet:

➜  phpcpd git:(master) phpcpd --log-pmd php://stdout --quiet /usr/local/src/phpunit
<?xml version="1.0" encoding="UTF-8"?>
<pmd-cpd>

    <codefragment>class BankAccountTest extends PHPUnit_Framework_TestCase
{
    protected $ba;

    protected function setUp()
    {
        $this-&gt;ba = new BankAccount;
    }

    /**

     * @group balanceIsInitiallyZero
     * @group specification
     */
    public function testBalanceIsInitiallyZero()
    {
        $this-&gt;assertEquals(0, $this-&gt;ba-&gt;getBalance());
    }

    /**

    public function testBalanceCannotBecomeNegative()
    {
        try {
            $this-&gt;ba-&gt;withdrawMoney(1);
        }

        catch (BankAccountException $e) {
            $this-&gt;assertEquals(0, $this-&gt;ba-&gt;getBalance());

            return;
        }

        $this-&gt;fail();
    }
