Pebble: Add support for dynamic Pebble background colors
- Add a couple additional icon types
- Add Lighthouse (currently unused)
- Add Transit (public transportation app)
- Tweak the colors on existing icon types
- Implement logic to grab primary (vibrant) color from app logo
- The color will be used when displaying a notification for an app
that does not have any configs bound to it.
- Alter NotificationType to support a color (named pebbleColor)
- Alter the Pebble notification poster to listen to the color from
the notification
- Alter the DeviceCommunicationService to allow for color passthrough.
- Add logic to convert HEX or Integer representations of RGB888 colors
to Pebble RGB222 format.
- make the package name retrieved lowercase.
