Customization class inverts the order of expected and actual parameters compared to other parts of the library

[janimationd]

The Customization.matches(Object actual, Object expected) method inverts the order of the parameters compared to the main compare methods, e.g. JSONCompare.compareJSON(String expectedStr, String actualStr, JSONComparator comparator) and JSONAssert.assertEquals(String expectedStr, JSONObject actual, boolean strict).

Please change the code to use a consistent ordering to prevent confusion when writing custom comparison Customizations.
