Invalid Change Music linedef executor will only ever work for a single player

EDIT: Okay, scratch that nonsensical bug report.

The Change Music linedef executor doesn't have a way to change the music for all players, unlike the Change Sky and Change Weather executors, which use the NOCLIMB flag for this effect.

May I ask why you'd be using those in a level load linedef executor anyway? Wouldn't just changing the map header info appropriately be easier in the first place?

This was a result of poor investigation, lack of communication, and general stupidity. Of course the executors aren't supposed to run at level load, because they wouldn't know which player to affect. And if you check the NOCLIMB flag, which makes them affect all players, they work fine at level load.

Sorry about this mess, but at least I found a quirk amidst all this. The Change Music executor can only affect the player who triggers it.

That makes sense, but there really should be a flag to check for all players. Just for convenience.
