Mutation Mod for Left 4 Dead 2

The changes include the following:

- Fixed several Mutations that use SaveTable() when the map transitions, it should no longer retain data from the previous map when you vote to restart or change campaign.

- Updated the HUD for many Mutations that use it. It should now prevent errors when trying to search for a survivor who hasn't spawned in yet.

- Added "Altered Genetics" officially, SI only that change their type when spawned. So a Boomer might count as a Spitter when killed and drop goo, etc.

- Removed the Prototype list from the menu, it was accidentally added in the previous update.

- Updated all VIP Escort modes:

The Survivor no longer loses his name and turns into a duplicate Bill if all survivors are incapped when the map restarts.
Made the VIP spawn with a medkit at the start of the first map only. No medkits will be given if the map doesn't allow medkits or if you've made it to the next map.

- Updated all United We Stand modes:

(United We Stand Realism): Added the missing mission files so the official L4D1 campaigns will work as intended now.
Made the L4D1 survivors spawn with a medkit for coop modes at the start of the first map only. No medkits will be given if you've made it to the next map.
Added a failsafe to force the Cvar "sb_l4d1_survivor_behavior" to 0 if it isn't already set. This prevents the L4D1 bots from running away on their own.
Fixed an issue with Zoey's item data getting lost if the map restarts due to all survivors being incapped.
Removed the extra weapons and items Zoey drops when the map restarts.
Added talker responses for the L4D2 survivors during the plane crash at Dead Air's finale.
Fixed the "PlayerFriendlyFire" responses for the L4D1 survivors. They will no longer voice those lines when taking fire damage.
