DOM concatenation utilities cleanup:

1. Extend `App.UI.DOM.generateLinksStrip` to accept strings as well as links.
2. Change calls of `App.UI.DOM.arrayToList` which added text-node pipes between links to use `App.UI.DOM.generateLinksStrip` instead, so they'll all pick up link strip styling should we decide to change it.
3. Move `App.UI.DOM.arrayToList` to use a similar fast Iterator-driven implementation to `toSentence`, and rename it `App.UI.DOM.toSentence`, since it really does the same thing, just with DOM nodes instead of strings.
4. Make Starting Girls use `App.UI.DOM.toSentence` instead of building the DOM committed slave list by hand.
