Upgrade to elm 0.19

- Greatly reduces size of state machine after compilation.
- Tests this time around found an inconsistency in how I was initializing the status bar.
- Removed extra code I found in resetStatus.
- Use new 'worker' program and call 'init()'.
- Found an unused import.
- Required unique name for port.
- Can't use shortcut '!' operator anymore.
- Require flags (empty in my case).
- Use new elm.json instead of elm-package.json.
- Use new elm commands in Makefile.
