Removing outdated preferences

- The namespace "http://registry.gpii.org/applications/fluid.uiOptions" was not official, so I'm removing anything in that namespace. 
- The OLB has no "captions" setting.
- Replaced unoffical "common term" tableOfContents with OLB counterpart.
- Removed other unofficial common terms (foregroundColor, backgroundColor, fontFaceFontName, fontFaceGenericFontFace, invertImages, adaptationPreference).
