Title: Add ListContributorsStats and ListCommitActivity for RepositoriesService

When you make a request for stats, you often get a 202 back at first (meaning the stats haven't been computed but now will be computed). I didn't do any extra work because I figured the user would rather be the one handling this (once you receive a 202, waiting ~1 second and then making the request again results in a 200).
