v2.21.0

• [Added] New extension 'ext-dnd5' for native HTML5 drag'n'drop support
• [Added] rtl option for right-to-left script support
• [Added] Add $.ui.fancytree.overrideMethod()
• [Added] hook treeSetOption allows extensions to update on option changes
• [Changed] standard CSS no longer defines overflow: auto for the container.
  If the tree container has a fixed height, overflow: auto or overflow: scroll
  should be added to make it scrollable.
  (Otherwise this always would be the scroll parent for ext-dnd5.)
• [Improved] better support for initializing from embedded JSON using the
  data-type="json" attribute
• [Fixed] corner case of #658 when ext-edit is loaded, but inactive
• [Fixed] #396 Don't load 'loading.gif' for glyph skins
• [Fixed] #675 ext-table: node.render(false) puts first node at end
