Get admin node deploy working-ish again, and fix a few nits. [3/5]

This pull request does the following:
 * Create an admin node record in the Crowbar databases by default
   when the crowbar barclamp is initialized.
 * Tweak barclamp_install to add the engine fragments to the master
   framework at package build time instead of install time. This
   leverages the engine cleanup that Adam added.
 * Fix a bug in CSS/SASS handling in engines that the previous change
   exposed. Engines need their own application.sass instead of
   application.css if they expose any sass fragments, and the do not
   seem to require their own application.css at all.
