[smokeping-users] units for rtt_max

[Paul Mansfield]

please can someone update the page
http://oss.oetiker.ch/smokeping/doc/smokeping_config.en.html

and specify what the units are for rtt_max, and whether it needs to be
an integer or fixed value?

it's possible to work it out through trial and error, but having it
stated specifically would be more useful.

thanks
