Rename/Move should be open buffer aware

[habamax]

If you rename files, all related buffers should be aware of it.

Single/multiple files/directorys rename, no corresponding buffers are opened in vim

Do nothing

Single file rename and a buffer is in vim and nomodified

buffer is invisible

• wipeout
• open renamed buffer as hidden (is it even possible?).

Maybe use file instead, to give a buffer new name.

Multiple files rename and there are multiple corresponding opened buffers

...

Single directory rename and there are multiple renamed files are opened in vim

...

Multiple directories/files rename and there are multiple renamed files/directories are opened in vim

For directories -- do nothing if they are opened in netrw. Only handle dirs opened in vim-dir
