Fix GPy.priors.InverseGamma ( #903 )
...
* 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

Corrected Multivariate Gaussian prior ( #775 )
...
* 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
