[feature request] Expand/contract directory in Tree without changing selection

[RussellAult]

Hi there!

In 1.0.6 (Debian stable), if you click on an arrow in the Tree to expand or collapse a directory, the directory that is being expanded or collapsed is also automatically selected. Is there a way to disable this, so that clicking on the arrow doesn't change the current directory selection?

My use-case for this is a single-panel file move operation, where I first go the origin directory to find the file, then expand directories in the Tree to find the destination directory, then click-and-drag the file from the panel into the Tree to complete the move. The current auto-selection behaviour is annoying because it means I have to re-find the origin directory in the Tree (and re-find the file) once I've expanded down to the destination directory, and selecting every intermediate directory clutters up the panel history so I can't just go "back" to the origin directory, either.

Thanks!
