Now the list highlights the correct lines on hover; previously it was highlighting the last cluster that appeared with the same timestamp. This has simplified some of the handling of objects.

The size of clusters above 10 events is fixed to grow continuously - 'max' is currently a useless measure as it is resulting in tiny blobs. Some overlapping is OK, so a better definition of max should be found. It's changed to allow growth to any radius now.
