FLUID-5161: Added ui options demo

Put the UI Options demo back and moved the preferences framework demo to a manual test.
FLUID-5178: Removed dependency on starterGrades

The auxiliary builder had a dependency on the startGrades.js file because it needed the defaultPanel grade. This has been moved to the Panel.js file and been renamed to fluid.prefs.prefsEditorConnections because it actually contains the configuration to wire up a panel to the preference editor.
