Title: Allow multiple messages in a single request to be marked as (un)read.

The reply by programmar on the thread, [How can I mark messages as read via the API?](http://www.reddit.com/r/redditdev/comments/o040t) made me realize that it wasn't currently possible to (un)mark multiple messages as read in a single request. This pull request allows for the desired behavior and, of course, also supports the current single message behavior.

I had a little discussion with ketralnis on IRC about why a developer may want to have this behavior. I came up with two such examples:

* Tool or Reddit client that allows marking all unread messages as read.
* Tool or Reddit client that automatically (un)marks all messages as read based on some filter such as the sending user, or subreddit the message belongs to.
