DeathCam Options Update

Another minor update. No bug fixes this time! Just a minor feature addition! :-)

- Removed a few leftovers I had tinkering around in player.h. An old enum and implement of that enum just chilling there.
- Added ability to switch "DeathCam" appearance in general settings menu. Now the user can have it:
    [Always] show, so no prompt will be asked upon death.
    [Ask] to show, the prompt we all know and love.
    [Never] show, revert back to pre-DeathCam days!

I tried to keep i18n in mind, but tell me if I missed anything else duders.
