Subject: [PATCH] Reduce volume of BGM and possibly other "noisy" audio since
 voice audio can't be increased.

Overwrites parts of the setup code in fw::CSoundManager::setupCategory() to not call GetCategoryVolume but instead use values we control. Parts of the original code (calls to GetCategoryIndex) have to still happen!

We're quite limited with the amount of space we have available to us. There has to be a better way...
