Track duration of page changes

Browse source 
The duration measured is between
 - componentWillUpdate of MatrixChat and
 - componentDidUpdate of MatrixChat.

This does not account for *all* changes to the view that occur
when a room switch happens, for example. But it does at least
capture the difference between switching to a "big" room and
switching to a small test room.
