Issue #23 Add test results history to TestNG view

Hi Cedric,

Please pull this code.

I noticed an issue with the progress bar not getting colored with the following simple test, but this issue existed even before this commit:
```java
package org.testng.prout;

import org.testng.Assert;
import org.testng.annotations.Test;
import org.testng.asserts.Assertion;

@Test
public class TestNGTest {

	public void prout() {
//		Assert.fail();
	}
}
```

Cheers,
Jean-Noel
