Release 2.4.0-rc.1

Changes between 2.3.6-beta.2 and 2.4.0-rc.1

• Bump ember deps to 2.10
• Bump froala-editor to 2.4.0-rc.1

Breaking changes between v2.3.5 and v2.4.0!!!

Because the version of this addon aligns with the froala-editor version, we could not release a new major version "out-of-line". Please note the following breaking changes to the {{froala-editor}} component;

• content is no longer updated by the editor, instead use an action to update the value. Ex:
  • From: {{froala-editor content=myProp}}
  • To: {{froala-editor content=myProp update=(action (mut myProp))}}
  • Alternate, "new" positional params option: {{froala-editor myProp (action (mut myProp))}}
• options changed post-initialization no longer updates the editor, instead use the related froala-editor methods
• Event handlers/actions on-*=(action) no longer receive an "event" object as the first arg, due to a change in event management. Change your action signatures;
  • From: function( eventObject, editorComponenet, ...params ){}
  • To: function( editorComponenet, ...params ){}
  • Similarly for the on-*-getHtml actions, but the eventObject is the second argument
• contentBindingEvent option has been removed, in related to the above content change
• defaultContent option has been removed, it was deemed unneeded and content is now set directly on the editor
• Previously undocumented isSafeString option was renamed to returnSafeString

content mutation was removed because it better aligns with ember's direction for "data down, actions up" (similar to ember-one-way-controls). This and unmutable options also removed the need to maintain other complex state management.
