Update includes database changes. You need to log all terminals out during upgrade

• Online backup status .Provide visual feedback in a terminal that a hot restore is in progress when reinstalling a c9 database from online backups. e.g.:
  
• New experimental optional statement format that prints statement in 'open invoice' style. Showing invoices and applied payments if any. i.e.:
  
• Email
  • added support for multiple email accounts.  Mainly intended for working around email systems that are very restrictive about From: addresses. e.g. outlook cloud email.
• Per customer profit summary
  • Allow generation of profit summary for a single customer. To access : view contact -> activity tab. Profit summary button there
• Smaller Tweaks
  • View Transactions. Include button to quickly access print statement.  Prints the statement in new 'open invoice' style defaulting to statement period of current month+prev month.
  • Receive order duplicate inv no check nag : make check case insensitive, so both 'test123' and 'TEST1234 match and will trigger the nag
• Bug Fixes
  • Updating c9 when using latest postgres database (10) fails to detect other terminals running, resulting in failing/broken upgrade processes. Now fixed as of upgrading to this version of c9
  • Unit deals. If you flip a unit on a deal to GST exempt and save it, it is impossible to flip the unit back to inc gst without removing and readding the unit onto the deal. Now fixed
  • Modify staff : missing a 'can process credits/returns' option on staff even though option was available in setup and was being enforced
