Summary: Add a sample selection method to random.py

Initial Comment:
random.randset(n, k) returns a k length list of unique 
integers in the range [0,n).

Improves on a Cookbook submission by using the 
parameters to select between a shuffle algorithm and 
a dictionary algorithm.

I want to add this to the library because it is a simple, 
robust solution to a general selection problem and 
because it isn't obvious that two different algorithms 
are needed to balance speed/space trade-offs.

If approved, will add docs and a news item.

Renamed to random.sample(n,k) to show that it is used 
for sampling without replacement.
