Fixes #514

[TheNormalnij]

Let's merge it with 1.6.1 release, to avoid potential regression.

@PlatinMTA found that Silver Vibrator ID 13 has been considered as an invalid ID (can't use in functions like giveWeapon and it's missing from the wiki weapons list!), but it's perfectly valid.....
So I updated IsValidWeaponID to not prevent it from being spawned, and now you can spawn a silver vibrator lol. Do note that it's always been a valid weapon ID on samp, with object model ID 324.

✅ Thanks @AlexTMjugador for noticing the need for editing pickup weapon object model ids lists
