Fixed issue which was preventing mutation modes from working

Map 4 - Finale - Worked on some issues with the nav spawning stuff too far away.

Made the vpk about 100 meg smaller.
Map 1 - Fixed some lighting issues on map 1.
Map 2 - Fixed a missing texture in a shed.
Map 3 - This map had some floating stuff. Made some map adjustments to compensate.
Map 4 - Opened up about 30% more map and removed about 3 layers of the map that weren't being used. I think they were confusing the director. Zombies are now spawning as they should. Removed some models that were put in the wrong family and were messing with the nav. Also made sure some models were put in the right family so they would show properly as they were invisible.

Updated map 1 with some better play around the gas station. There was something weird with the doors that were making them unbreakable. Now the undead can come eat you better. Also fixed all the unbreakable windows and walls in the house / garage in front of the house downstairs. Put level 1 guns on map 1 and the beginning of map 2. Updated map 2 with some new models. This removed the need for having about 300 mb of extra models / materials in the game. Now the game size is 322mb versus 600mb+ that it was. Updated map 3 to be closer to the original with a barricade and more of a feel of coming out of a warehouse into a warehouse environment. I think the flow is much better. Updated map 4 with an ammo pile and removed the "survival stuff" off the map which was overkill for items. Also fixed some nav spots that I overlooked. Should make it more of a challenge. If you find anything else me know. I'm off to get eye surgery tomorrow so might not be working on this until the end of the week? Just have to see how I feel. :)

Silly me, I play on a server with all 8 characters and forgot to make this campaign L4D1 survivors. Now you can hear the dialogue.

This needed a lot of love to get going but here it is, in almost all it's old glory. Since map 3 is the same as map 2 of beginning hour I just went ahead and copied off it what needed changing over. Everything else is the same except for having l4d2 items. I fixed the nav, textures, models, whatever needed fixed and got this puppy working. Please feel free to let me know if I missed something. This was tested on a modded server and is fun as hell. Especially the warehouse. I removed the pylons around the gas stations because they would work intermittently. One minute there, and one minute not. I think the model is faulty. Well enough talk, have fun.
