ntpmon now has some keystroke commands

All that is too much to remember.  I have just made the spacebar rotate
through all three modes.

? is already done.

I had it working like that for a while.  The problem is that there is no
way to satisfy all three of the following constraints:

1. ntpmon options have the same semantics as corresponding ntpq options
2. option letters are the same as the corresponding command keys
3. commands are natural mnemonics in English

The simplest way to get to a consistent UI design was to remove all
command-line options.  Which is a good idea anyway - less to remember,
and the command keystrokes cover the functionality.
