-removed "additionalInfo" nested dictionary, leftover from ZMQ days
-removed debug line in setup.html which was updating devices section with people coordinates
-merged "sendDeviceInfoToServer" to "registerDevice", renamed locator.initDevice to locator.registerDevice
-registerDevice now adds device type to clients list
-renamed route "sendOrientation" to "updateOrientation"
-replaced most reference parameters from requestHandler from device.ID to socket.id, matches style used for all other client types (eg. webClient, sensor)
