src/test/: Add webapp.php, which contains a special test-harness that can be extended to provide a slick/simple interface for testing webapps that use the spare-parts webapp "framework".
Add src/database/paranoid.php, the very beginnings of a "paranoid" layer for database access, to limit the type of content that can be saved to the database (so far, explicitly limiting angle brackets to avoid malicious HTML code -- i.e., <script> tags) from making its way into the DB.
