Ecopath: Diet composition table

[villyc]

When editing the diet composition there is no reference available of which predator (name) one is editing -- one has to find the same row number to read it. In EwE5 I had added the name of the current consumer in the status bar, we need something similar or smarter.
Also, I changed the row color for the current row to make it easier to see what prey is being edited.
Using the same background color for the diagonal and for the current cells is a bit confusing.
The last diet row with (1-sum) is smart, but not very useful when editing a large diet composition: For such the EwE5-way of showing the balance in the status bar is neater.
