Working on shaders and the core game mechanic

I carved some sand details into the ground. Added a blob shadow for the palm.
The shield and axe now uses the metalic and smoothness property of its shader.
The shader for the palm, ship and the player has now more emissive power.
The UI for chopping has its first draft but Sebastian Irmer makes us some nicer wooden board soon. Chopping levels up a multiplier on the base weapon damage on the tree.
