Don't allow users to request aliases, implications, or renames for invalid tag names. As a side effect, it's no longer possible to request shortcut aliases like `/hr -> hakurei_reimu` (slash abbreviations still exist, but they can't be overridden with aliases). Tests involving these types of aliases are removed.
Config
This directory contains configuration files for Danbooru.
To configure your Danbooru instance, copy danbooru_default_config.rb to danbooru_local_config.rb and edit it. See danbooru_default_config.rb for details.
The only file here that end users need to be concerned about is danbooru_default_config.rb. The rest of the files here are internal Rails-related configuration files that end users shouldn't need to edit.
