Update v84: more bugs fixed. — Planetary Exploration Company Steam update #399508

Improved: 1. Eat tooltip: added tooltip for the "eat" symbol. 2. Weapon box location: the robot will not launch a weapon box below the robot, so its easier to see now. Fixed: 1. Research tutorial broken: in the research tutorial, you could make the next workshop tutorial to not show correctly if you clicked the wrong button, so now you can click on only 1 button to avoid errors. 2. Exploration tutorial hidden: in this tutorial you could hide the button that the tutorial was refering to. 3. Destructable bar: sometimes when you started to destroy it, it wouldn't stop and the bar didn't dissapear even when you walked away. 4. Explorer sprite direction: the sprite did not change directions when using the keyboard keys to move. 5. Role window tooltips: added missing employee tooltips. 6. Fire employee crash: sometimes when you tried to fire an employee the game crashed.
