Cleaning API and documentation, more work on serial interface

Driver.java
-now extends Runnable, drivers only need to implement ControllerModule or SensorModule
-changed receiveMessage to receiveCommand to match naming convention

LedFlash.java:
-no longer implements Runnable

SimpleDriver.java:
-no longer extends Controller
-no longer implements Runnable

StatefullLed.java:
-no longer implements Runnable

Coordinator.java:
-list of loaded drivers now stored in a hashmap
-added broadcastCommand()
-readSerial implemented (not tested)
-sendCommand() changed to a wrapper method, checks current protocol version and routes message to sendCommandV0() or sendCommandV1()
-added sendCommandV0() to send command as protocol 0 message: [destination | ':' |command | '\n']
-sendCommandV0() re-encodes message as US-ASCII from Unicode
-added sendCommandV1() to send message as protocol 1 message: [start_byte | destination | ':' | command | '\n']
-sendBinary() implemented (needs to be updated to detect protocol version)
-storeData() and readData() broken into text and binary versions

SerialConnection.java:
-attempts to connect to a preferred connection before trying from a static list

SimpleHttpServer.java:
-added empty class for testing
