mutation mapper selection button behavior on first click

[inodb]

Would it be possible to have the first click select the mutation type you are clicking on and deselect everything else? Currently the mutation type you click on becomes unselected with everything else selected, which is the opposite of what the behavior was before

Yes, we can do something like this:

if (all selected)
    deselect all except the clicked one
else
    toggle the clicked one
