Also, since the root component connects to the stream that updates home/notification columns,
there is pretty much no case for refreshing those columns beyond initial load. So, move the
loading of those columns into the root component, to prevent unneccessary reloads when switching tabs
on mobile or resizing desktop window between mobile/desktop layouts

A couple of places were using "reblog" rather than "boost" - this updates them to match the web UI

in the column and what appears as desktop notifications. Settings do not
persist yet
