Many small bugs fixes

First of all, big thanks to Matt, who played the game on he's Twitch Stream recently and to all players, who had a blast by making a mess in multiplayer game - that was fun! In this "quiet" update, most of the bugs, pointed by the Stream viewers, was eliminated. Fixes: - Player model are now hidden and you can only see other players. This was done to reduce "flicker" and to prepare the way for VR implementation. - Players now can lift (in theory) another player's forklift. - Cargo break sound can be changed in SFX settings. - Pallet kinematic fixed, no more floating pallets. - Reset / Menu / Cancel now working on small screen. - Forklift controls disable while typing in chat. - Chat disappear speed is now slowed down. - Chat now have sound. - Breaks lights. - Controls are polished for use with searing wheel. - Electrical forklift have correct engine and fork operating sound. (More polishing needed) And of course - explosives!
