Allow adding nested files and folders in `Add File` and `Add Folder` modal

[LakshSingla]

Nature of issue?

• Found a bug
• Existing feature enhancement
• New feature request

Feature enhancement details:

Current To add files and folders in the directories (i.e. to nest them) one has to manually click on that folder and click on the New File or New Folder button. Adding files as FolderName/FileName won't nest it in the FolderName folder and instead create a new file named FolderName/FileName in the same directory.

Proposed On entering FolderName/FileName, new file named FileName should be created in the FolderName if it is present in the currently selected node. ( Likewise while nesting folders in folders)

Points of Discussion

• What should happen if FolderName is not present under the current node? Should one implicitly create it or ask the user?

I think this is a great idea! I'm not sure how to handle the case if the folder name is not already present, though I just checked how Visual Studio Code handles this, and it automatically creates the folder(s) for you.

@catarak I would like to start work on this issue. If anyone has claimed it, please lemme know, so that we are both not working on overlapping things.

@LakshSingla as far as i know, no one is working on this! i see you already started working on it, so that's great.

@catarak I have moved the discussion to the Pull Request #767. Please check it out for my concerns :)
