Left 4 Bots (Improved A.I.)

This addon improves the survivor bots behavior to make them more human-like and a bit more useful during the game as well as improving their combat skills.

- MAIN FEATURES
• Survivor bots can pick-up and use defibrillators
• Survivor bots can pick-up throwable items (pipe bomb, bile jar and molotov) and throw them when needed
• Survivor bots might decide to give their throwable items to human survivors when they aren't in fight
• Human survivors can give their throwable items to any other survivor just like they do with pills and adrenaline
• Human survivors can swap their throwable items with a survivor bot
• Survivor bots pick-up med items more efficiently without waiting for humans to pick them up first and leaving medkits behind
• Survivor bots can scavenge and pour gascans.
• Survivor bots can deliver the cola bottles.
• You can order the survivor bots to hold their position with the vocalizer command "Wait here".
• You can order a certain survivor bot to crown a witch.
• Survivor bots will not heal themselves if they have 60+ HP (usually they do this in the start saferoom) unless there are enough medkits around for the teammates who need it and the bot to pick-up
• Survivor bots react faster, aim better and will try to help more
• Survivor bots will try to dodge the spitter's spit as soon as it lands at their feet and before they get the damage (they can still step on in later tho...)
• In "The Sacrifice" finale you can order the suvivor bots to activate the generators all together using the vocalizer commands "Lead" and "Go". You can use this to unlock the "Chaos Generator" achievement in singleplayer.
• In "The Sacrifice" finale, when the bridge is lowered, you can order one of the suvivor bots to push the button to raise the bridge by using the vocalizer command "Lead".When the button is pressed you can order one of the bots to go restart the sacrifice generator giving the highest priority to Bill for the "Kill Bill".
• Other minor improvements
