Silent Hill Scrap Collection

v0.1.5.81

Reduced max volume of radio by 31% and changed pitch range to be less ear-splitting (retained some ear-splitting charm)
Tweaked reflectivity/normals of radio
Altered several loot values again based on feedback (for example, steel pipe is no longer worth a pittance)
- Same with item weights--some have been altered where I deemed necessary. Full changes are visible in the updated README on the main page.

Added radio noisemaker scrap
- Unfortunately the newly-added UseCooldown field in LethalSDK doesn't seem to function yet, so this sound clip has been cut very short to prevent awful audio spam. When LethalSDK updates this field, I'll change the radio audio.

Added 4 more scrap: blood pack, flip lighter (zippo), silver medallion, gold medallion
- Silver and gold medallions are very valuable, but very heavy and rare!
Rebalanced all the scrap values again, tweaking them down to more realistic numbers
Adjusted gasoline tank handheld position to block your view better >:)
Made new, real sfx for the gasoline tank to replace the placeholders
Tweaked a bunch of sfx (added a new item drop noise, adjusted volumes, trimmed excess, etc.)
Fixed gasoline tank normal map
Fixed steel pipe normal map
Altered glass bottle normal maps
Beat my head against a wall for several hours until I realized LethalSDK can only export 15 items per .lem

added 4 more scrap: rubber ball, video tape, first aid kit, and gasoline tank
adjusted scrap values to be more consistent with spawn weights (items are more valuable overall)
tweaked some spawn weights
added proper steel pipe swing sfx
balanced all sound effect volumes
fixed some normal maps not working
removed accidental oldseaport dependency by including select normal maps
