Restored heightmap functionallity
Created branch to work on heightmap that is stationary but changes as the texture changes.
Calculate height map now moved to compute shader. A lot of refactoring and fixing stuff. Added hud class but no functionality.
Added shader functions to inline functions in shader code. Not super clear but gives clean shaders at least. Adds to all shader stages.
Fixed compute shader reload not working. Fixed normal calculation in compute shader.
Merge branch 'heightmap'
Fixed feet that follows ground. Also removed some coupling in camera class that is unwanted.
