Combined water and earth fragment shader main parts, since they need each other anyway for lod smoothness.
Implemented normals for water (which can not really be seen at the moment).

implemented height check in water and earth shaders to color the fragments according to their actual height
even if the geometry is wrong due to unprecise tesselation when looking from great distance

instead of implementing the functionality themselves
(will probably be needed for easy comparison: waterlvl vs terrainlvl
to improve lod-smoothness)

WASD and arrow keys controls now Pitch and Yaw of the spaceship, Q and E Roll.
+/- on the Keypad and Y and X control speed. Somehow, Y is not working...

Also fixed the error in the moonshader.

some reorganization of the planet-shaders to improve code-reusability and easy adding of differently looking planets
