Assert "isCloseTo(double expected, Percentage p)" doesn't work for negative expected values
I have two tests whether an actual value is within a given percentage of the expected value.

The test for a positive expected value works without problems.
The test for a negative expected value throws `IllegalArgumentException`

My test methods are:

```
@Test
public void checkPositiveNumber() {
    assertThat(11d).isCloseTo(10d, withinPercentage(10));
}

@Test
public void checkNegativeNumber() {
    assertThat(-11d).isCloseTo(-10d, withinPercentage(10));
}
```

I've tested only for doubles but I suspect the same problem exists for all numeric types.
