Modifications in TCP sockets and RFID tags

The TCP socket connections of the collectors where not being able to identify a abrupt connection lost and was creating undefined behavior. We decide to create a message of synchronization to keep the socket alive as along as the collectors send a answer a message to the server.

We modify the module for MRI2000 to send the correct information to the server, and we created an utility function to abstract the RFID tag from the "application code"  and "identification code"
