Animations

• Added smooth crouching and looking out. Speed can be adjusted with g_cam_height_speed and g_cam_lookout_speed commands. I have set the default values to my taste.
• Added support for inverse kinematics for NPC/actor models so they can walk properly on uneven surfaces. To work you need omf animations for NPCs with kinematics support. A beta version of such animations can be downloaded >>here<<. These animations changed by @D1m0n93. I will update them if there are new versions. You can also use animation files from other mods, in which kinematics works.
• Transferred camera effector system from OpenXRay. Added support for actor motion animations anims\\\camera_effects\\\\actor_move\\*, the effector of landing after a jump is now working.
