Improve factlog command

Now, by default, uses concise timestamp relative durations; e.g. "2d5h ago"
instead of "2 days and 5 hours ago".

Now, by default, shows only nick instead of full hostmask for each entry.

Now accepts optional arguments -t and -h to control the above behavior.

If -t is specified, then it shows a full timedate instead of a relative duration;
e.g., "Sun Dec 13 14:26:56 PST 2015" instead of "2d5h ago".

If -h is specified, then it shows the full hostmask for each entry instead of
just the nick.
