• Bump croner from ~4.1.x to ~5.0.x
• This bump enables croner legacyMode, which make expressions behave like "classic" cron when combining day-of-month and day-of-week. See croner feature #53 for more details.
• Croner export is normally named Cron, Changed one occurence of Croner() to Cron() for consistency.
