HUD Color Issues

Some users have reported inconsistent behavior when trying to change the hud color for a specific pilot.

- [x] HUD Colors selection should be saved in the PLR, and possibly also the CSG
- [ ] HUD colors should load the user's preference on every boot up of FSO
- [ ] If Hud colors are saved within CSG's as well, then those should be used every time switching campaigns or multiplayer
- [ ] `.hcf` files should be saved within the `/player` director within AppData.
