improved script

[blondon1]

retry mechanism for the connect_to_server function with a delay between attempts, broader error handling for sockets-related errors, added a simple way to exit the loop and close the socket connection properly, the sending function now accepts the socket object as an argument, improving its independence and reusability.

While this seems as a good project, someone seeing it for the first time might not understand what it does, would suggest adding a README file with a description of what the code does.
