ib: never relay "Warning:" errors to EMS..

You'd think they could be bothered to make either a "log" or "warning"
msg type instead of a `type='error'`.. but alas, this attempts to detect
all such "warning"-errors and never proxy them to the clearing engine
thus avoiding the cancellation of any associated (by `reqid`)
pre-existing orders (control dialogs).

Also update all surrounding log messages to a more multiline style.
