Feature request: Hightlight/Select previous folder after navigating upward.

Have an option to highlight the folder I navigated up from, whenever Up is used.

This has become sort of essential in my mind, especially when working with folders which have many subfolders.

Was feeling this and realized because Windows Explorer has this feature.

Hurrey, it's working in the latest AppVeyor Snapshot. (version 1.4.0.1879) Link to AppVeyor Snapshot: https://ci.appveyor.com/project/derceg/explorerplusplus/builds/41424895
