The documentation no longer built, due to a series of missing files and

fixtures, incorrect metadata, and bad references.
This change fixes all that by:

Adding fixtures for issue verification state, OAuth2 apps/tokens, and

  user-based file attachments
Adding missing API error and resource doc files
Adding missing terms to the glossary
Fixing metadata issues in new API resources
Fixing the fixture dump script to include the new apps
Fixing syntax errors in docstrings
Fixing anchor names

It also fixes some bad filenames generated for the OAuth2 resources. The

uncamelcasing tried using "o-auth" instead of "oauth" in the filenames.

To fix this, support has been added for allowing names to be remapped as

needed in the config file.

Built the docs. There were still a couple of errors, but they're bigger

tasks that we've lived with until now. All the major ones preventing doc

building or cross-referencing are now gone.
