Updates to home-doc link parsing

Per #6 ...

1. Regenerate fixtures to remove deprecated links
2. Fix the `documentdelete` vs `documentsave` thing
3. Remove the last of the hardcoded links
 * lookup `issuetoken` and `listcredentials` in the home-doc
 * avoid an endless loop by not requiring a token for home-doc fetching
4. Fix tests (mostly for number 3)
