move TICKIT events out of error.log

If you get feeds from multiple hubs, you're likely to encounter something like

evnt TICKIT "WW240806.ZIP" already exists in "/sbbs/data/dirs/fidonet/fidoweathe
r/", but has no matching Replaces line   

I've got almost 1000 of these logged since 6th August and they're really not life shatting errors. I would prefer these to be logged where other events are logged.

Personally, I think error.log should be for system breaking stuff, type errors, programs crashing and the like.
