Eelco Dolstra f729f12e4e Some cleanups in the activation script:
* Moved some scriptlets to the appropriate modules.
* Put the scriptlet that sets the default path at the start, since it
  never makes sense not to have it there.  It no longer needs to be
  declared as a dependency.
* If a scriptlet has no dependencies, it can be denoted as a plain
  string (i.e., `noDepEntry' is not needed anymore).
