Title: Changed repositories.UpdateComment to use a struct.

In response to [a discussion](https://github.com/google/go-github/pull/41#discussion_r5877562) with @willnorris in issue #41

UpdateComment now takes in a RepositoryComment instead of a string for a
parameter. This makes it easier to support more data types if/when the API
changes.
