A lot to ContextRxStuff. Gotta start checking in more granularly.

* Added ColorMappings, AppCategory to try to centralize colors...much to do.
* Removed CancelAsync(ms). All cancellation is done through the token.
* Streamlined a lot of Cancellation stuff.
* Corrected References to account for no longer using subscriptions.
* Tweaked logging/add detail to summary info
