* Update setup.py
remove special handling of scipy dependencies for old python versions
* Update __init__.py
replace numpy type by native type
* replace np.bool by bool
If you run mpiexec -n 2 on any code to try to use MPI multiprocessing for SparseGPRegression, it crashes (see #618) because the rank>1 processes do not have ret defined.
This PR adds two main things to GPy:
- to- and from-dict functions for the kernels listed belop
- a fix for the appveyor CI
Please see the squashed commit messages listed below.

* new: added to_dict() method to Coregionalize kernel class
* new: added to_dict() method to MixedNoise likelihood class
* fix: made Y_metadata dict content serializable
* fix: typo
* added additional needed parameters to to_dict() method for Coregionalize kernel + added _build_from_input dict method
* new: added possibility to build MixedNoise likelihood from input_dict
* Y_metadata conversion from serializable to np.array when loading from dict
* fix: rework Y_metadata part for compatibility with unittests !minor
* conda cleanup in appveyors pipeline
* conda clean up after conda update
* conda clean before conda update
* try pinning packages for conda
* revert all conda changes
* conda clean all (not only packages)
* use conda update anaconda
* pin conda package
* pin conda package
* try installing charset-normalizer beforehand
* try to get from conda-forge
* revert all conda changes
* Try to fix the conda update challange.

It is just a try for a different context/(conda version).
* Still fixing build error on appveyor
I also use a newer miniconda version for greater python versions.
* Update appveyor.yml
Thinking it over it decided to use miniconda38 for all python versions unless python 3.5.
* revert miniconda versioning changes
* adjust GPy version in appveyor.yml
* 1st attempt bring the appveyor build to life again
* #955 fixing ci build on appveyor
After bringing the miniconda env to work again, the wrong matplotlib version was used. This commit should fix that.
* #955 Fix CI build
Freezing numpy and scipy was a bad idea.
I freeze matplotlib dependend on the python version only.
* add: built_from_dict method for White Kernel

* fixed InverseGamma prior: beforehand, it was a child class of Gamma but it defined a broken __new__ method of its own. Now, it just inherits Gamma's __new__; also added a test that ensures the InverseGamma can be instantiated and integrated into a GPy model
* overwrote misleading inherited methods in InverseGamma, deleted unnecessary repeated code
Removed indication in docstring that was incorrect: `kernel` is a required arg, but docstring stated it was optional. Now, docstring does not say it's optional.
* Corrected MultivariateGaussian prior
Some corrections including adapting to current version of pdinv, correcting the expressions of constant, pdf and its gradient, and adding the printing function. After some tests, seems to run as expected, similarly to the Gaussian prior which was already working.
* Added test of MultivariateGaussian prior
Simple unit test for creating a kernel with Multivariate Gaussian prior over the lengthscales, then performing GP regression.
* Took care of case where x of shape (n, 1) for multivariate Gaussian prior
* Got rid of unnecessary asserts in Multivariate Gaussian prior since loss of time
