/*
(Date unknown) - Jezu@Astaria
Added error_handler() during porting to FluffOS
July 10, 2022 - Jezu@Astaria
- Refactored error_handler().
- Fixed bug in error_handler() that was incorrectly applying verbose_errors.
- Changed debug class for errors generated by wizards to be ':<wiz name>'. This is so wizzes can selectively enable which wizards they want to receive errors for.
