Galleries look slightly better

I have fixed a long standing 'irritation' with the member galleries; the thumbnails would not flow nicely depending on the relative heights of thumbnails/descriptions in each row of the gallery.

For a long time, I have been trying to fix this with pure CSS, but it seems it's just not possible to have a liquid floated div 'table'. Instead I am now using a bit of onubtrusive javascript to fix the layout, see my other blog for details.
