TYPO3 Core

When trying to move a page (a) after another page (b) that has already been moved in the workspace, the page (a) isn't moved to the correct position in the page tree. Instead, it is moved just after the position where page (b) has been before it was moved itself (ie. the position of (b) in the live workspace).

I'm attaching a patch that at least fixes the problem when using drag and drop in the page tree, I'm not really sure if I found all code parts where pages are moved.
