Yancy-1.013

Changes for version 1.013 - 2018-11-09

Added
- Yancy backends now ignore some database tables by default. These tables are:
  - mojo_migrations - Used to track database migration versions
  - Minion tables (based on which backend you're using)
- Added documentation site example. This will (eventually) be used to build a Yancy documentation website.
Fixed
- Fixed OpenAPI spec to remove unused "Array" items. Thanks @mohawk2!
- Removed deprecated PODRenderer plugin in examples. I have created a fork called PODViewer.
- Fixed documentation for Standalone mode to make it easier to use.
- Fixed detection of `UNIQUE` keys in SQLite. SQL is case-insensitive, and SQLite's table schema is just the SQL used to create the table, which we parse to create the JSON schema.
- Fixed a problem with Postgres tables having multiple unique keys.
- Allow `id` values to change when editing. This fixes multiple problems in the editor and the backend that were activated as a result of trying to edit the `x-id-field` values.
- Allow `/` in `id` values. This allows paths to be used as IDs, which is crucial to making an easily-editable website.
Other
- Work has been started to separate the Yancy editor into its own Yancy::Plugin class. Thanks @mohawk2!
- Removed a UTF-8 character from some documentation. The Mojolicious::Plugin::PODViewer doesn't correctly say that it's sending UTF-8 data, and the Mojolicious::Command::export doesn't correctly decode/encode UTF-8 data.
