update UI: checking if the device is online every 1s in MyDeviceFragment : 1 if the device's control type is cloud, it will always be online. 2 if the device's control type is local, it will be online only if its mac,ip,port are all same in trackingList.

device will be added into trackingList if 1. the device is not added yet AND 2. its already in saved list AND 3.the conltorl type is local control 

related function update: when repairing device (that ip or port changed): remove the device (with old ip or port) from DeviceList first and add the device (with new ip or port)

Changed the condition to add a device to tempList: 1) if the mac is not already in tempList AND 2) the mac is not found in saved list or the mac is found in the saved list but device's port or ip has changed

removeDevice() -> add  transientListRemoveDevice(mac) &  trackingListRemoveDevice(mac)

turn on/off of mDNS discovery periodically

changes in TcpThread:

05-11-2015.a:
updated: functions in trackingListFindDeviceOnline()
removed device list length check in both MyDeviceFragment & FindDeviceFragment - > UI is forced to update periodically
-- local link done

05-11-2015.b:
updated pairing() function, add support of pairing cloud controlled device
renamed all "firebaseAccount" to "firebaseAppId"
in FidDeviceFragment: + add getFirebaseAppId() function
add activity class : RegisterFirebaseAccountActivity

05-13-2015:
updated UI and function for cloud device pairing (need test):
    if device is a cloud controlled device:
        --> a pop up EditText dialog will prompt to user to enter the firebase app id
        if user doesn't have a firebase account:
            --> RegisterFirebaseAccountActivity will start and open firebase registration page
        --> start pairing process (3-handshake-pairing)
    else start pairing process directly (2-handshake-pairing)

investigate the JmDNS crash problem:
--> on/off mdns discovery service frequently can increase the change of crush
    --> the cause of crush is related to listener socket binding
        --> solution not found yet, debugging ...

05-15-2015.a:
important update:
JmDNS crash problem solved:
    +JmDNS discovery service is turned on once and continuously checking txtRecord change
