Minor changes

I've slightly changed the format of the 'Watching' section of the sidebar, so as well as just being a list of the last five films I've seen at the cinema or on DVD, there's also a pithy review of each of them, should you care to know my brief opinion. I considered introducing something similar for the books and music parts just above but as stuff tends to go on there before I read and listen to them, rather than after as in the case of the films, it would get too confusing keeping track.
