* Move the definition of the set of system packages to

Browse Source 
modules/config/system-path.nix.  system/system.nix is now almost
  empty.
* Removed the cleanStart option - it should be possible to get the
  same functionality by overriding config.system.path (or defining
  config.system.systemPackages with a higher priority - don't know if
  that works though).
