Add Option to Sort Page Tree in the Sidebar

Currently it's possible to sort the Page Tree with a few different options such as position, creation date, modified date, etc. However, this option is only available when using the Page Tree macro.

The purpose of this suggestion is to implement this functionality in the Page Tree located in the sidebar too, since the only sorts available now are the alphabetical order and the manual one.

e.g. If I want to see the recent created pages in the top of the Page Tree in my sidebar, it's not possible right now.
