Some improvements to file/dir open/save dialogs:

1. Removed "..", instead you now will see "Select Current Folder" and "Select this Folder" buttons.
2. Added "go to parent folder" (^) button to Save a File dialog.
3. Tree.cpp: "nothing_selected" signal has been re-made (previous implementation, merged in #13308, wasn't optimal in context of performance)
4. Fixed issue in Project Export dialog: MODE_SAVE_FILE wasn't set when you click "Export".
5. Now you can deselect items by clicking on empty space in Open a Directory dialog.
