compare changes

I broke compare.html. Now when a button is clicked, it takes a long time
to load, and then it doesn't apply the supp/opp correctly.
compare work 02

Added console debug to compare.html
compare work 03

Finally got compare.html to add and remove support and oppose as desired
compare work 04

Made the columns of compare.html split the window

Copied code for remSupport and remOppose from the first table cell to
the other three so that all of them work now.
