Ability to ignore "Confirm Cancel"-warning on dialogs

[Henrik Helmø Larsen]

If changes have been made to a dialog and the cancel button is pressed an annoying "Confirm Cancel" warning is displayed. It would be nice to toggle weather you want this warning or not.

The new "on cancel event" on the dialog will look like:

this.on( 'cancel', function( evt ) {
  if (!editor.config.ignoreConfirmCancel)
    iterContents( function( item ) {
      if ( item.isChanged() ) {
        if ( !confirm( editor.lang.common.confirmCancel ) )
          evt.data.hide = false;
        return true;
      }
    });
}, this, null, 0 );

The only line added is:

if (!editor.config.ignoreConfirmCancel)

which is in line 323 of the plugin.js in the dialog folder. This is just before the iterContents( function( item )... is called - thus ignoring this check if the ignoreConfirmCancel is set in the editors config.

In order to toggle the warning add the following line to the editors config:

config.ignoreConfirmCancel = true;

IMO it can be annoying after some time of working with dialogs, so the option to choose whether you want these confirmations or not is a very good idea (at least for me).
