## About The Pull Request
- Makes use of the byond internal optimization for `view` to speed up
aura healing a tiny bit.
- In case you didn't know, byond has an optimization for `view` which
speeds up iterating over objects in view if you provide it a type. This
use of a ternary (likely) prevented this optimization from kicking in,
and since worst-case we're doing view(7) it can add up.
- Test case: 2 staff of Ascelpius users surrounded by 15 humans and 15
random objects constant being damaged. ~8 minutes of testing.

```
- Generalizes `SSaura_healing` to `SSaura`, makes "damage aura"
component (which is totally 99% copied from "healing aura" but that's
for another pr) use it as well
