Passed every png file through http://www.smushit.com/ysmush.it/ saving some 1-2kb of binary image data

This reverts commit 48714142.
Additionally there is a new fix for FS#2107 that doesn't introduce a lot
of checks but instead ensures that the configuration option can't be set
to negative values when the configuration manager is used.

This fixes an infinite loop in breadcrumbs() and makes the behaviors in
all places where breadcrumbs are used consistent so that non-numeric
values, values < 0 and 0 are treated the same way.

Template authors might need to adjust their CSS

FS#1874: removed padding for interwiki links in print stylesheet, as the icons aren't displayed there

This introduces a new function called tpl_flush() which should be used
by template authors in favor of the PHP flush() method.

It is now possible to use the %f placeholder in $conf['dformat']
to add a fuzzy age string.

Template developers and plugin authors should replace their strftime +
$conf['dformat'] calls with calls to the new dformat() function.

Example:

   %Y/%m/%d %H:%M (%f) produces dates like this:

   2009/09/16 10:36 (3 weeks ago)

This adds a new link wizard to the toolbar which helps users to find the page the want to link to.

Pages can be found by a simple page name search or by browsing the
existing namespaces.

This is the first checkin. Some cleanup and MSIE compatibility checks
remain.

This patch enhances the code and file syntax with several new features.

1. code and file are now essentially the same and just differ in the class
   name. This means you now can use the file syntax with syntax highlighting
   as well. This also solves problems where the code to highlight already
   contains a <code> tag (FS#1493)

2. a filename can be given as label for the code or file block. It is
   specified as second parameter after the language:

   <code html myfile.html>...</code>

   If no highlighting is wanted, but a filename shall be given, you can use
   a dash as language:

   <code - somefile.foo>...</code>

3. when a filename was given (as shown above), the label links to a
   download of the code given in the code/file block. This is made possible
   by a new renderer in inc/parser/code.php. The basename of given filename
   is suggested as filename when downloading.
