Created a function to verify if we are connected to an EOS console

[jasonappah]

I created a function so it would be easier for the future addition of commands.

I added

def verifyConnection(self):
		if client_connected:
			pass
		else:
			raise ValueError("Not connected")

Now, instead of

	def go(self):
		if client_connected == True:
			client.send( OSCMessage("/eos/key/go") )
			return 1
		else:
			raise ValueError("Not connected")
			return 0

We can do

	def go(self):
		self.verifyConnection()
		client.send(OSCMessage("/eos/key/go"))
		return 1

I also reformatted the code. I made this a draft PR as I haven't been able to test with an actual console, although I have tested with Nomad. I will test with an ETC Ion after the winter break, and update the PR after I do that.
