Single Grab Weapons After First Saferoom

tl;dr

Makes weapons single grab after you leave the first saferoom you load in to. Once any player exits the starting saferoom all weapons on the current and remaining maps and saferooms become single grab. Ensures everyone gets to start with a gun.

-The first saferoom doesn't necessarily mean "first level's saferoom". It's the first saferoom of whatever level you choose to start on.

-This also affects the infinite pipe/molotov/pill boxes found on The Passing.

Why I made this alternative to the original

In the original Single Grab Weapons mod you slowly build animosity towards your friends when they reach the gun table before you. After several campaigns you get in to arguments over who gets to start with a gun. You start doing bad things like refusing to rescue friends who get picked by specials just so you can grab their gun when they die.

"Mom said it's my turn for the gun!!!"

No more of this, now everyone gets a gun when we start.

Thanks to RainyRayne for making the preview icon. Thanks to Nescius for the original idea and figuring out how to prevent dropped weapons from being absorbed by spawners.
