Module header tidyup, phase 1

This patch is a start on removing import lists and generally tidying
up the top of each module.  In addition to removing import lists:

   - Change DATA.IOREF -> Data.IORef etc.
   - Change List -> Data.List etc.
   - Remove $Id$
   - Update copyrights
   - Re-order imports to put non-GHC imports last
   - Remove some unused and duplicate imports
