Add server (web/socket), create socket system, better helper loader.

- The Magic Mirror is now hosted via a express server, allowing you to
load it from an external client (for debugging.)
- It now includes a socket system to communicate between the
node_helper and the client module.
- node_helpers are now only loaded if the module is configured in the
config.
