KRACOEUS-8002 fixing protcol schedule attachments

This was broke in 5.2 as well.  I had to create a new sequence object, and add a member variable CommitteeScheduleAttachmentsBase for the schedule ID.  Please be sure to double check my sql scripts for creating the sequence.  My first SQL changes in a while, and I want to make sure I did it correctly.
Yes.  Please reduce the length of the sequence name
