[Foldit] Close ligand design panel when action isn't possible
The Ligand design panel saves its visiblilty state when switching puzzles. This is a problem when you switch between puzzles where the tool is or is not availible.
We had previously added code to turn off the panel for non-ligand design puzzles. However, we missed the case where the puzzle is a ligand design puzzle, but the ligand design panel tool is turned off (in the puzzle setup).
