+/**
+ * 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.
