Description of problem:
The config properties used by CMS have an overly verbose naming
convention, of the form com.arsdigita.cms.ContentSectionConfig.XXX.
Including the name of the config class itself is overly verbose, so
they should be shortened to com.arsdigita.cms.XXX or perhaps
com.arsdigita.cms.section.XXX if we anticipate the need to for
properties not particular to a content section.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Done in the APLAWS WP3 branch land.
