Removing some global variables in the distrib package



Hello,

I want to add some new probability distributions to the distrib package, 
but at the same time I think I could remove all global variables of the 
form 'random_*_algorithm'.

The selection of random simulation algorithms was introduced for 
comparative purposes; the default values for these variables make 
reference to the fastes ones, so I think I can remove the others.

I don't think these changes will break anybody's code.
