[Adv Wide HUD] Hide target screen button when HUD is minimized

When using the Adv Wide HUD, hide the target screen button when the HUD is minimized (but make sure it is hidden on startup when minimized too, see 0x004E1C3C, and 0x53C450). At 0x004E1C3C, `esi = HUD_Target*`

Here's a patch for hiding switch to target:
```

000E3939:8D->6A
000E393A:44->01
000E393B:24->90
000E393C:0C->90
000E393D:50->6A
000E393E:6A->01
000E393F:06->90
```

Notes:
```
TargetStatusHandler* - 0x384 = Target*
Target* + 0x38 = HUD_Target*
[HUD_Target* + 0x4A8 + 0x15C] = SwitchToTarget*
```
