The Tree node has the ability to jump to a specific item by typing the first few chars of it's name.
But on selection ('item_activated' signal), it didn't clear the search string used for that. It was especially annoying in `FileDialog`s and has been bugging me for
ages :P
With this, you can traverse a directory structure in a FileDiag quickly with the keyboard (like you'd expect from pretty much any modern file browser) :)
