Augment "Rename selected file" to create directories that don't exist

Let's say I have the following directory structure:

```
dir1
    file.md
dir2
```

If I rename "dir1/file.md" to "dir2/file.md", it will successfully move file.md from dir1 to dir2 and I will end up with:

```
dir1
dir2
    file.md
```

If I try to rename "dir1/file.md" to "new-dir/file.md", I would like it to end up as:

```
dir1
dir2
new-dir
    file.md
```

However, it ends up being a no-op from the file system POV, and in nvultra, it shows the rename in the left hand side file list, but you see an empty text area to the right.

Can nvultra create the "new-dir" if it does not exist?
