Sorted the messages by timestamp, from newest to oldest. - RMUR
Adding a filtering system that's not plugged in yet. Should be easy to
use a filter on a collection and get a smaller set of wisprs. Should
also be easy to use a filtr to highlight wisprs that meet certain
criteria in the GUI. - RMUR
Added a few new filtering objects.
