to fullfill mixer implementation requirements
*Added FBM2D, first complex noise class of the new architecture
*Removed NoiseMachine, because was redundant and not fitting with the new
architecture
*Minor changes to almost every other noise class (mostly adding 'this->')
everywhere an inherited member from template base class was called from
the inherited class
*MappedNoiseBase provides a gain and offset control on the noise value
*AbstractXDNoise provides a way to contain different noises in a std
container and access the main "GetValue" member function
*Applied minor optimisation to Perlin4D (previously forgotten)
