Remove the log switching cacophony on startup

Remove the log switching cacophony on startup

Resolves the first complaint of #103:

Looking back at the history, it seems these messages were born because
a long time ago, sys-logging was hardcoded to "server" mode, while
console "logging" was tied to "standalone" mode. Default was "server,"
which meant a newcomer who managed to kickstart Fort in the foreground
with minimal arguments ended up with a validator that, on account of
looking silent, seemed to be doing absolutely nothing.

Given than logmode and runmode are completely independent now, and log
output defaults to "console," it would appear that these messages are,
as a matter of fact, completely useless.
