More game stuff

Worked a lot on the game at the weekend but have very little to show for it :)

Re-modeled / textured the cliffs and the cave, cave texture is still horrible but I quite liked how the cliff came out

Mainly worked on the code side, hooking up the hud graphics to the art so it's all functional - also made some fairly major changes to how the camera system works (camera now follows the player vertically so it's always at the same height relative to the player, and also follows the player moving backwards)

Next up I need to model a new item crate, a signpost, a tree stump and some boulders that match the texture of the cliff!
