Started work on RPC support.

* Including DCKeyValueObjectMapping CocoaPod
** This will enable us to serialize objects to JSON (to send over the
wire) easily-er.

* Began work on RPC support
** This introduces three new basic object types: MCSRequest,
MCSRequestOperation, and MCSResponse.
** MCSRequestController and MCSRequestHandler are the two classes
responsible for interfacing with these classes on the Client and Server
respectively.
** There is a lot of copypasta that I do not like. Room for improvement.

* Changed example app to be a collaborative list. Clients and the
localhost can add items to the list.
** Currently the only item that can be added is a test string.
** Currently only the server refreshes content. Events will be added
soon, which can be data that is sent from the client to the server
(such as the list refresh, in this case).
