- add scripts/remove-boot-splash so we can modify a bootsplash

  from an initrd without having to rebuild it
- make-boot-splash doesn't try to detect the resolution anymore,
  it now needs to be given one
- in switch-themes and remove-theme, use bootloader-config to update the bootloader
- remove detect-resolution
- requires new mkinitrd (old mkinitrd used detect-resolution)
- remove "Patch: glibc-fixed-header.tar.bz2" which is unused (and not in CVS)
