[1.30] Preload() and Preloader() don't do anything

[AbsolutePsycho]

From my tests both Preload() and Preloader() don't do anything in Warcraft 1.30.
Or at least, in regard to sound files. Preloading sounds doesn't work.
Maybe it's a bug or Blizzard disabled something recently.

Zero effect from calling this:

call Preload("Test\\file0018.ogg") // audio format doesn't matter, same zero effect with MP3 and WAV

Doesn't matter if it's a direct call or it's done via some Preloader("list.pld").
I found temporary workaround. This can be used now to actually preload sound file:

call GetSoundFileDuration("Test\\file0018.ogg")

You can see that it works, because the game freezes for a few moments, if the sound file is big enough (for 2+ Mb OGG file it's easily noticeable on my PC).

As for Preloader(), it doesn't seem to execute ANY code from withing the file. Just nothing.
