Upgrading to v3

• $diffOptions removes: charLevelDiff and separateBlock.
• $templateOptions adds: detailLevel (similar to charLevelDiff, read docs) and separateBlock (exact the same one in $diffOptions).
• Jfcherng\Diff\Diff's $a ($old), $b ($new) are required in __construct(). (You may pass two empty arrays if you do not want to do anything at that moment.)
• The look of "skipped" block in HTML renderers (SideBySide and Inline) have been changed. (You may have to tweak your CSS.)
