- Support more lenient usernames and group names in FTP servers
- Fixed `MemoryFS.move` and `MemoryFS.movedir` not updating the name of moved
resources, causing `MemoryFS.scandir` to use the old name.
- Make `WrapFS.move` and `WrapFS.movedir` use the delegate FS methods instead
of `fs.move` functions, which was causing optimized implementation of
`movedir` to be always skipped.
