- Fixed: Cheats in demos must not access the weapon slots.

- Fixed: S_ChannelEnded didn't check for a NULL SfxInfo.
- Fixed: R_InitTables did a typecast to angle_t instead of fixed_t.
- Fixed: PowerProtection and PowerDamage applied their defaults incorrectly.
- Fixed: The damage type property didn't properly read its factor.
