this work exposed a few bugs and slow spots, which have been fixed
for the aol page, I added some additional backwards compatibility code
to proportionately distribute width when a fixed-width cell has colspans
1. cellmap couldn't properly delete CellData because definition was unavailable
2. optimized table cells made taller wouldn't shrink when they should because we were not
remembering the previous desired height of the cell.
3. rows were placing cells on the left edge, and not adding in the left margin.
