Select attribute type form bootstrappin

I think I've got this one all there. The only thing that's questionable is there were some conditionals stopping sorting, usually related to if display_asc was set: if ($akSelectOptionDisplayOrder == 'display_asc') { }. Which I kind of understand, but it isn't set when you first add the attribute, so you couldn't sort them at that point. So I just removed those, as I think the "option order" options are verbose enough that folks won't get confused and say "hey, but I sorted them!" if they've got it set to most popular or alphabetical. It just seems like if we wanted to go completely that route, you'd disable drag-sorting dynamically based on what the "option order" select value was currently or was changed to, but that seems kind of like overkill to me. But I'm happy to revise.
