*Seed is uint instead of int
*Permutation table is uint instead of int, could lead before to program
crash with negative seeds

this commit will change the scale of values produced by fbm2d. This will
probably not happen again. As a consequence, fbm values will always be
constrained between -1 and 1, but do not perfectly stick to that scale.
There is no easy solution, if the user wants the best dynamic between -1
and 1, he should adjust manually the value by multiplying by a gain slightly superior to 1.

*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
