Fixed server loop

Fixed client echo to accept more than 1 line and not block on 1 client.
Now allowed multiple clients to connect, send as many lines as they
want and then handles disconnects.
Client updated to echo 5 items
Changed Output Method

Curses is apparently not thread-safe. Switched back to STDOUT.
Server now uses a control thread to update the number of clients
connected.
Added -some- error handling. more needed
Time Function + Code clean up

Server & Client:
Added time function to return the system time (format YYYY-MM-DD
HH:MM:SS)

Server:
- Removed commented code from prior prototyping implementations
- Cleaned up program output
- Added a class hash to keep track of output messages and corresponding
functions to control it

Client:
- Code comments
- Timestamps for some output
