Fix regression in code Refs #4569
fixes #4675 Adding new config file setting:

; By default, users can create Segments which are to be processed in Real-time.
; Setting this to 0 will force all newly created Custom Segments to be "Pre-processed (faster, requires archive.php cron)"
; This can be useful if you want to prevent users from adding much load on the server.
; Note: any existing Segment set to "processed in Real time", will still be set to Real-time.
;       this will only affect custom segments added or modified after this setting is changed.
enable_create_realtime_segments = 1
