When redirecting to a page, use an absolute URL.
This fixes a bug when redirecting from a sub-page (since,
in that case the redirect happens before the <base> element gets
sent.)

New methods:
WikiDB::set($key, $val)
WikiDB::get($key)
To support global meta-data. Before you make use of these methods,
please consider that they are implemented in a somewhat
hackish manner, and are not likely to be very efficient.
New methods:
WikiDB::getTimestamp()
WikiDB::touch()
To support the notion of a global timestamp on the WikiDB.
In WikiDB_Page::set():
Delete special magic for setting 'pref'. Currently, this appears to
be either unused or broken (since 'pref' seems to be set to a
serialized value.) In any case, this magic shouldn't be here.
If you need special handling put it before the call
to WikiDB_Page::set().

Starting to fix handling of the HTTP validator headers, Last-Modified,
and ETag.
Last-Modified was being set incorrectly (but only when DEBUG was not
defined!) Setting a Last-Modified without setting an appropriate
Expires: and/or Cache-Control: header results in browsers caching
the page unconditionally (for a certain period of time).
This is generally bad, since it means people don't see updated
page contents right away --- this is particularly confusing to
the people who are editing pages since their edits don't show up
next time they browse the page.
Now, we don't allow caching of pages without revalidation
(via the If-Modified-Since and/or If-None-Match request headers.)
(You can allow caching by defining CACHE_CONTROL_MAX_AGE to an
appropriate value in index.php, but I advise against it.)
Problems:
o Even when request is aborted due to the content not being
modified, we currently still do almost all the work involved
in producing the page. So the only real savings from all
this logic is in network bandwidth.
o Plugins which produce "dynamic" output need to be inspected
and made to call $request->addToETag() and
$request->setModificationTime() appropriately, otherwise the
page can change without the change being detected.
This leads to stale pages in cache again...
These deal with setting the Last-Modified and ETag headers of the
HTTP response. They also parse and handle the conditional request
headers 'If-Modified-Since', 'If-Unmodified-Since', 'If-Match',
and 'If-None-Match'.

Usability improvements for the RedirectTo plugin.
(Mostly this applies when using RedirectTo with a page=OtherPage
argument to redirect to another page in the same wiki.)
(Most of these ideas are stolen verbatim from UseModWiki.)
o Multiple redirects (PageOne -> PageTwo -> PageThree) not allowed.
o Redirects are not activated except when action == 'browse'.
o When redirections are disabled, (hopefully understandable)
diagnostics are displayed.
o A link to the redirecting page is displayed after the title
of the target page. If the user follows this link, redirects
are disabled. This allows for easy editing of the redirecting
page.
FIXME: Stylesheets, and perhaps templates other than the defaults
will probably have to be updated before this works well in other
styles and/or themes.

For use when expansion of a plugin is disabled.
This displays a message (like WikiPlugin::error()), and also

However it seems that the only code affected is this file is currently
