#51 On/Off switch to show/hide "future" dated posts

[straightgeek]

To resolve the issue of persons sending updates from
locations that are in different (i.e. future) timezones
than the server running their install of comoblog.

e.g. I am in Texas which is in the Central US timezone
(GMT -6), my server is located in California which is
the US Pacific timezone (GMT -8). When I would send
entries to my comoblog they would not post for 2 hours.

The change made to include/libraries.inc.php by Mark
Wallis temporarily resolve the issue. Thanks.

There is a "where date < current timestamp" SQL clause in
the library call that gets the top x posts. We need to
make this SQL call option.

1. Add new parameter to base XML
2. Add new parameter to upgrade script
3. Add if clause to library.
