New version

I uploaded a new version. There are some fixes and some additions too.

• fixes for the algorithm that calculates how deep the light from the surface reaches
• fixed changing mouse and gamepad sensitivity settings not doing anything
• added a mechanism that prevents the sky from showing when the terrain is culled by occlusion culling, now the bright sky won't be hurting the players eyes that got used to the darkness for a split second while additional terrain is not visible yet
• the player model receiving ambient lighting now depends on the given cube at its position and not on being over or under the surface
• fixed lit surfaces not casting shadows by surface lights
• fixed running stopping when the player is moving down a slope and is not grounded for a second
• lowered step volumes for a bit
• added some missing sounds: walking on sand, dropping onto sand, climbing ladder
• removed number of rays settings for the occlusion culling system, it wasn't doin anything anyway
• fixed the scrolling of the load game list not working by enabling the scrollbar
• fixed sorting of saved games in the load game menu, now it's sorted by the number and not alphabetically
• added a permanent scrollbar into the shop and inventory window, so the list items don't change width when the scrollbar appears or disappears
• added a way to rotate the weapon and the plans of the placeable objects by lowering the input frequency, e.g. rotating the mouse wheel slower 
• also added a game manual some days earlier both an English and a Hungarian version

Enjoy!
