Adapted client to use Ncurses instead of raw terminal output:

Created "slowPrintNcurses", which is a version of "slowPrint" compatible with Ncurses screens.
Ncurses is now used in place of raw-terminal output.
The screen clears after inital start-up messages.
C-d no longer exits, and still doesn't spam.
Added Ncurses to the ld options of client in the Makefile.
Created ld options for server in the Makefile.
