* Fixed a reorganize bug that led to pages with the same rank; run node app apostrophe:repair-tree and then you shouldn't have to do so again. The problem was caused by two things: (1) nudging ranks upward for pages that used to follow a page is unnecessary and introduces bugs with the calculation of the page's new rank if it is remaining a child of the same parent. (2) re: nudging the successor pages downward... always specify multi: true, dummyhead.
