Upgrading to v4

• Jfcherng\Diff\Utility\SequenceMatcher becomes a new package by the namespace of Jfcherng\Diff\SequenceMatcher.
• Factories under Jfcherng\Diff\Utility\ are moved to Jfcherng\Diff\Factory\. For example, Jfcherng\Diff\Utility\RendererFactory is now Jfcherng\Diff\Factory\RendererFactory.
• Non-abstract classes are no longer inheritable as they are added with final keywords. (This allows me to do more internal changes without causing possible BC breaks.)
