WP/PHP compability updates, code standards compilance fixes.
This is almost a patch rather than a minor release, but the minimum requirement changes warrant it.
- Confirmed compatibility with WP 6.6 and PHP 7+, likely some deprecated warnings in PHP 8.
- Touched up a few edge cases such as undefined values or query mods being called on secondary queries.
- Localization fixes for a handful of strings.
- Thorough escaping on PHP output wherever possible.
- Attempted to fix as many WordPress coding standards errors as possible; most remaing errors/warnings are false positives.
- Much improved documentation on Registry and Translator methods, the overloaded methods like get_post_sync_rules and get_post_language are properly documented now.
