OVOS Shell companion

provides various bus APIs that integrate with ovos-shell

- color scheme manager
- notifications widgets
- configuration provider  (settings UI)
- brightness control  (night mode etc)

these used to be several individual plugins but they all are ovos-shell specific integrations and ovos-shell requires all of them, so they have been unified
