if autogenerated <options>/checkboxes only work on every other search/render

[jeremybmerrill]

then put it in a setTimeout(function(){}, 0) so that the template is rendered first, then the autogen stuff checks for whether the /checkboxes are present in the page. (Otherwise, as is the case right now, the "old" options are still in the page, as the template is evaluated before replacing it, so the check doesn't work.)

ooh, maybe I should put the setTimeout in the generateOptions function, to reduce the boilerplate in user-written templates
