All click to (un)equip all actions

[andriusch]

It's a bit janky since it has to unequip them one by one but it works. I used alt since it's quite destructive operation, and there's lower chance of alt being clicked than others. Fixes #38

@andriusch skillActions.fromEvent(e).toggleVisibility();

is the only code needed to resolve the conflict here correct?
