* Updated to ZDoom 4242:
- Be consistent with whitespace tabs.
- Stylistic changes.
- Fixed: A_RemoveSiblings and [A_RaiseSiblings] did not check that the caller had a master to deduce siblings from.
- Fixed: WeaponGiver did not give half ammo when dropped.
- Fixed: The constructor for single-lump fonts did not initialize the Cursor field.
- Added a NODELAY state flag. This is only valid for a state immediately following a Spawn label. When set, the actor will run this state during its first tick. This means Spawn states may now run an action function if you set this flag. Note that this action function is executed during the actor's first tick, which is not the same as when it is spawned.
- Fixed: r4226 [ported in r1557] had bad copy-paste angles for Demon2's XDeath.
- A_KillSiblings and A_DamageSiblings didn't check for a valid master.
