Hayt avatar & other things.

"Centered" prawn default mbulmer; fixed dllcc_elevator, added hayt.

Further edits to avatars & backgrounds.

Fixed a few BGs; centered a couple more avatars and put feet on the
ground where appropriate.
A few background edits.

Proposed deletion of a couple of crappier backgrounds and another
tweaked image.
