Changed where in the code the row are reveresd
(wrt scrolling lists) so that the most recent
messages are on the bottom. The rows are now in
the correct order from getRows, rather then
updateRows. #18.
Made the EventListController use domain and range types, rather
than severity, domain, and event message. This allows it to be
more generalized, which should be helpful with different data
formats later on. #18.
When viewing an event message generator new messages are now added to the
bottom of the display, rather than being added to the top and pushing
the other messages down by one. #18.
