TS TestAI, more BaseProvider logic, and more.

Fix `GAPOWR`.
Fix `PROC`.
Add `Guard`/`Guardable` to `^Helicopter`.
Add `GASILO`.
Add TS Test AI

`^Building` now has `FrozenUnderFog`.
```diff
BaseProvider:
+ bool UseRange
+ bool RenderRange
```
Not sure what's happening then because I intentionally played multiple games without cheats. I'll look into it.
