Mask adjusting/flipping for breath and sterile masks

- Added for breath mask/medical mask, sterile mask, and balaclava
- When adjusted, you can eat shit and your identity isn't hidden, but the mask is unusable
- Usually changes the sprite to wear the mask on your head / hang it around your neck
- Made the sterile mask hide your identity (you can move it out of the way now)

Some questions that will be asked:

**Why did you remove the ability to push the gas mask up?**
Well, because, pushing the gas mask up when you were wearing a hat looked silly as fuck. It clipped through the hat. The gas mask is strapped to your face, period. This way, the breath mask has an advantage over the gas mask as well, moving it out of the way to eat, where the gas mask processes toxins better. Additionally, it made all children of gas masks have useless action buttons on them, which is bad and explained below.
**Why no verb?**
Because I've come to hate object verbs and adding more object verbs is a slippery slope into it being more cluttered than it already is. I might even change the jumpsuits to use action buttons instead of object verbs as well, eventually.
