Safely lazy load claims and reserved lists (#1177)

* Safely lazy load claims and reserved lists

This moves the entries of all of these lists into "insignificant" fields and
manages them explicitly.

* Additional fixes

Fix a few problems that came up in the merge or weren't caught in earlier
local test runs.

* Changes for review

- removed debug code
- added comments
- improved some methods that were loading the entire claims list
  unnecessarily.

* Fixed javadoc links

* Reformatted

* Minor fix for review
