CameraSetting.settingFlags

[Dragorn421]

• Rename CameraSetting.unk_00 -> CameraSetting.settingFlags
• Add macros for accessing settingFlags (CAM_SF_UNK0, CAM_SF_UNK1, CAM_SF_PRIORITY)
• Add macro for packing settingFlags (CAM_SF)
• Use CAM_SF to pack flags stored in sCameraSettings.
  Note instead of directly using CAM_SF in sCameraSettings I define the flags as macros then use them in sCameraSettings, like we do for actor flags in the actor profiles
