Reduce size of usernotes data
Several changes for 1.5

- Work for compressed usernotes. (Not completed.)
- Added TBUtils.pageOverlay for long operations.
- Updated TBUtils with new versions and schema vers.
- Added TBUtils.clearCache
- config.js clears cache on all wiki changes

Usernotes are currently broken, as a result of the schema changes.
Needs some work/testing.  If you're running the live dev, do not change
usernotes or any config options.
