Adding printer to cups

v1.4.1

Added code 39 support

v1.4.0

Rails 5 Upgrade

Usage Metrics

Added PSD Logger for recording of usage metrics.

API only

Split front end from back end.
The front end (Ember) is now in it's own repository (print_my_barcode_frontend).
The back end is now API only.

Meeting JSON API spec standards

Error format to match JSON-API standard,
Print Job to return 422 when input is incorrect,
When creating a resource successfully HTTP status should be 201,
Printer resource allows creation of printers with protocols other than LPD.

Encoding Fixes

Info in files sent off to LPD will be encoded with CP-850. Fixes issues with characters such as µ and ° not printing correctly.
