 * ITFlow - Database update to version 3.6.0 (from 3.5.9)
 * Included by admin/database_updates.php - do not access directly
 *
 * Text messaging (functions/sms.php):
 *   sms_providers - the texting service ITFlow sends and receives through (Skyetel), its
 *     keys, the number it texts from and the key in its inbound address
 *   sms_messages - every text sent and received, and what came of it: queued, sent or failed
 *     going out; on a ticket, in the Texts inbox (unmatched, a code, spam) or a keyword coming in
 *   sms_numbers - what is known about a number: a name for it, whether it replied STOP, and
 *     whether it is blocked as spam
 *   settings.config_ticket_sms_parse, config_ticket_sms_unknown_senders, config_ticket_sms_acknowledge -
 *     Settings > Tickets > Text to ticket
 *
 * Re-runnable: each table and column is made only where it isn't there yet.
