optimalization of screen-output of ntpmon

[folkert]

Hi,

Tried to create a pull-request via gitlab but that failed in mysterious
ways. So that's why I'm also sending it via the mailinglist (I talked
about it on irc as well).

Subject: [PATCH] Use stdscr.erase() instead of clear: erase is more efficient
 while effectively doing the same. https://linux.die.net/man/3/werase says:
 "The clear and wclear routines are like erase and werase, but they also call
 clearok, so that the screen is cleared completely on the next call to
 wrefresh for that window and repainted from scratch."
