Bug Fixes and Minor Adjustments

• Fixed cash drawer opening to work in 64bit by sending the drawer command as special characters via the printer.
• Changed to cache 20 of the most recent transactions rather than 10. Will now also save those even if p10 crashes/force closes.
• Fixed: quick build wasn’t showing correct Units Available.
• Fixed: message on the email when making a Confirm link was mentioning payment if the partial payment request was enabled.
• Fixed: previous change to how transactions save was preventing it from showing some messages given during posting.
• Changed Production scan keyboard shortcut to be Alt+Comma since some scanners can’t do multiple modifiers.
• Fixed: having a long user name was preventing some actions in Paradigm.
