words: make alternative relationships two-ways

The 'alternative' relationship was only being created on a single
direction when calling 'words dup', while in this case it should go both
ways so the 'words show' command can pick things up easily. Considering
how I don't think I'll have too many words to begin with, this sort of
duplication shouldn't be too troublesome, and it makes code easier.
