use /slashes/ as leading/trailing tokens for stems

If an item has a morph type of stem, using /slashes/ as leading/trailing tokens in headwords.

This convention is specific to Algonquian, so later we'll need to make this customizable per-language.

My take: The slashes in the Algonquianist tradition don't actually represent that something is a stem. They represent that something is an abstract representation, and it so happens that stems are conventionally written in an abstract representation by Algonquanists (e.g. broken down into the three components).

The leading/trailing tokens for stems are nothing for the leading token, and a hyphen for the trailing token.

So I won't implement this, but will mark stems as abstract instead, when they're given broken down by morpheme.
