Tweak to case check trigger to allow user to bypass the safety
feature by including the token BYPASS_CASE_CHECK in the changelist
description.
This is likely useful just after initial rollout of the CaseCheckTrigger
on an existing server that already contains case inconsistencies.
Bypassing the trigger may be required to do some cleanup of existing
data.
If this trigger is deployed on a new server initially, the bypass may
not be needed.
