Add file logging handlers to default configuration.

We're having problems with the syslog handler in our logging
configurations and as at least a temporary measure we'll begin using
flat files instead.  This should get us the appropriate debugging
information we need.
Update SysLogHandler arguments for *nix.

The default configuration for SysLogHandler assumes that syslog is
listening on a local UDP port.  We'll change that to use the datagram
mechanism provided through /dev/log instead.  While we're at it we
update the logging facility to daemon from user.
Increment the patch level.

We've made minor changes to the logging recipe but nothing that should
break the way logging is handled (just provide more information).  We've
also made it easier to switch to syslog if desired.
