Subject: Allow manually creating watch_later entries

This commit introduces the "add" command which allows the user to create
watch_later entries manually. Make sure to silently ignore entries that
already exist - we'll print the entire list of entries subsequently
anyway. Also, make explicitly specifying "add" optional if there's any
remaining arguments in argv.
