Updated to server version 0.003. Modified serialization from pickle (binary coded) to JSON (text coded). I'm hoping this will allow us to edit text files directly, if we want to, rather than create a whole in-browser editor. JSON files can cause problems with data structures though, so we'll see.

Also started mapping out functions for future implementations (arrow key movement, servo displays). Need feature requests here from what we'll need here. Feel free to place some command structures in there.

Server-side development of servo actuation is now on hold until the implementation of Raspberry Pi --> Arduino communication API.
