Fix a handful of failures and regressions in our docs.
Review Request #913 - Created Oct. 13, 2017 and updated
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. Testing Done: 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. Reviewed at https://reviews.reviewboard.org/r/9238/
