* Remove redundant call to resolve-allof
All of the callers to resolve-additional-types already call resolve-allof (or
if not, they should), so this is redundant.
* Update `resolve-additional-types` to take a dict
I want to add more params to this, so first make it take a dict.
* `render-object-table`: take a "title" rather than a "caption"
... which means we can use the result from resolve-additional-types directly.
* render-object-table: support adding an anchor to generated tables.
* resolve-additional-types: generate an id for each returned type
* render-event: pass an anchor_base into resolve-additional-types
This means that it will generate an anchor for each type, whihc will then be
passed into render-object-table and used as an `id` for the table.
* render-operation: pass an anchor_base into resolve-additional-types
* newsfiles
