Consider adding File / Folder to notify::EventKind::Modify

[wiiznokes]

I would like to watch directories and files that are renamed. But impossible to make the difference between a file and a folder with the existing api. I have no idea if there is a reason for not adding the File/Folder enum but it would be very useful.

I just realized that there can't be a folder and file with the same name on unix while writing this issue, but I'm still using this info in my node search function.

See #476

I could only see this happening for the debouncer-full
