* Fixed some stretched textures so that they match up ✓

^ Expanded on NPC relations; now not only will combine soldiers and the helicopter be okay with you, but roller mines, gunships and more won't attack you either ✓
^ More detail and textures have been added ✓
^ Many textures have been tinkered with so that they appear more natural ( i.e the sidewalk ) ✓
^ Distant buildings have had a facelift ✓
^ Moved the clips that prevent players from walking down the roads further back ✓
- Removed some corners on the fences, to allow more areas for combine and zombies to traverse ✓
- Removed the APC and its wheels in spawn having physics; they are now unmovable ( for gameplay reasons ) ✓
