Aimbot/silent aim: settable FOV, FOV circle, target locking

- Aimbot -> FOV and Silent aim -> FOV values (1..180 deg from the crosshair)
- Aimbot -> Show FOV circle: projects the FOV cone through the engine's
  world->screen transform (hidden for >=89 deg since the boundary is behind
  the eye)
- target lock: while a feature has a bind and the key is held, the acquired
  target is kept while it is alive and has a visible selected hitbox point;
  it only re-acquires when the target dies/leaves visibility or the key is
  released. With bind = None both features keep selecting the nearest target.
