Graphics Update, Performance Improvements, Nav Mesh fixes.

Hello all you people. Apologies for the long silence, had some things take priority over everything else. Today's update is a small or big one, depending on what you place importance on in gaming: -After quite a few comments and reviews stating dissatisfaction with the resolution and visual design of the game, I've made efforts to improve on both. It's still a work in progress, but I've made pretty substantial improvements to ground textures, rock textures, and the overall look of the environment. Things should now look far more natural and realistic, hopefully improving on immersion. -Fiddling with the occlusion, I've managed to increase performance, which should improve jittering for some systems. -Fixed a nav mesh issue that was causing pathing issues on the Huntsman level for NPCs. Please leave feedback if there are any issues, in the Steam forum preferably. -P
