• For live.list, queue all removes and adds in the ListDOMPatcher together, and perform removes and adds when the dom queue is flushed.
• For live.html, move updates from the notify queue to the dom queue; do adds right after removes when queue is flushing, rather than enqueuing again.
• Add guards to the range helpers so they do not attempt to iterate removals on ranges that have already been torn down (i.e. when the start and end nodes no longer have parents nor siblings)
• do patch sort on each patch passed into live.list rather than attempting to sort all patches (prevents "Could not group patches" error when 3 or more patches are dispatched)

Closes #150
