Shorten complicated path for u_playSound

[Morxemplum]

When making longer sound buffer names to try and combat ambiguous naming and minimalize conflicting IDs, solving this problem created a new one. u_playSound requires you to input the full sound buffer name in order to find the sound and play it. But when applying this with the new disambiguator, author name, and version in it, this can start spiraling out of control really fast. I'm raising this issue to hopefully simplify the syntax for u_playSound so ideally all you'd need to put in is the name of the sound in the "Sounds" folder of a pack.

In addition, solving this problem can also make sure that packs cannot leech into other packs and steal their sounds.
