Feature Request: Recycle Bin / Trash Usage

[TheExpertNoob]

For deduping, if the OS supports it (and user permissions support it), in undupe.py add the library
from send2trash import send2trash (of course this also adds a new library in requirements)
and replace os.remove(file) with send2trash(file)
May make for a "safer" undupe between a dry run and complete deletion.
