Subject: [PATCH] Merge ticket thread tables into one (2 of 2)
Add SQL patch file and update the main install SQL (MySQL) script to
transfer messages, responses, and notes into the new ticket_thread table.
For new installations, transfer is not necessary because there are no
messages

+/**
+ * Merge ticket thread tables into one
+ *
+ * Replace the ticket_{message,response,note} tables with a single
+ * ticket_thread table that will contain data for all three current message
+ * types. This simplifies much of the ticket thread code and paves the way
+ * for other types of messages in the future.
+ *
+ * This patch automagically moves the data from the three federated tables
+ * into the one combined table.
