Added several new calls and properties:

 * Post.ApprovedBy (a string)
 * Subreddit.GetModQueue () -- returns a Listing<VotableThing>
 * Subreddit.GetUnmoderatedLinks () -- returns a Listing<Post>

These will likely only work for mods, as I implemented it for a modbot.
Fixed formatting issues. Thank you, MonoDevelop. x.x
Moved some of the global methods to AuthenticatedUser per recommendation.
Fix more formatting issues and tackle the hardcoded string I left in.
...I hope this solves the last formatting issues...
