Revert "linux.conf.au 2009: Tuz"

This reverts commit 8032b526.

Hey, it was only meant to be a single release.  Now they can all die as
far as I'm concerned.

[ Just kidding.  They're cute and cuddly.

  Except when they have horrible nasty facial diseases.  Oh, and I guess
  they're not actually that cuddly even when disease-free. ]

Documentation/logo.txt

-Tux is taking a three month sabbatical to work as a barber, so Tuz is
-standing in.  He's taken pains to ensure you'll hardly notice.
+This is the full-colour version of the currently unofficial Linux logo
+("currently unofficial" just means that there has been no paperwork and
+that I have not really announced it yet).  It was created by Larry Ewing,
+and is freely usable as long as you acknowledge Larry as the original
+artist. 
+
+Note that there are black-and-white versions of this available that
+scale down to smaller sizes and are better for letterheads or whatever
+you want to use it for: for the full range of logos take a look at
+Larry's web-page:
