*Since only valid template parameters were float and double, the whole
template aspect has been removed.
Double precision would only be used in extremely rare occasions
(applications needing high precision and slow performances), it is not
relevant to template the whole module for it.

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)
