I've had a look at the System Configurator man page, and I've done some
thinking about where it's appropriate to have this support.  I believe
that it's better to execute the postscripts directly from the
autoinstall script.

Here are my thoughts:
- Postscripts may do _anything_, and are not necessarily related to
 configuring the system.  One of the postscripts I'm going to put
 immediately to work in my environment is an xcat postinstall script
 that tells xcat to boot the node normally after install, instead of
 installing it again.

- It may prove useful to have pre-scripts, and mid-scripts, and other
 kinda scripts at some point, and it would be nice to be able to
 implement them in the same way.  Unfortunately, if we use System
 Configurator to call those scripts, we're limited to running scripts
 on a machine that has completed it's imaging, or we need to find a way
 to include System Configurator in the boel_binaries tarball.

- I don't believe this adds complexity. As it turns out, the way the postscript support is currently implemented, I believe we actually have fewer lines of code than before. This is primarily due to pulling all scripts at once (autoinstall and post), instead of trying several pulls until we get a hit.

- The additional lines in the autoinstallscript.conf file amount to
 this:

 #####################################################################
 #
 #   Post Install Scripts

Thoughts?
