Some issues with the FCK editor

Reported by Charles (Rutgers):

• it puts in a separate copy of the javascript functions for each editable item on the screen
• show/hide is cheesy. It doesn't actually remove the editor. It just collapses the toolbar. But it still takes the same amount of space.
• if you edit a quesiton and save it, and then edit it again, you get the editor window, and there's no "show/hide" option
