EPIC - Application UI/UX redesign

[DropSnorz]

The last UI update has been published in OwlPlug 1.25.0, mostly to get rid of the deprecated JFoenix component. Small improvements as been made to the UI but there is still a lot to do.

A global overhall of UI/UX would be something to consider along with some refactoring on the app presentation logic.

• More use of the declarative pattern
• Remove or Replace deprecated component in owlplug-controls
• Explore a way to easily reference SVGs and configure viewport for application assets. Check this demo
• Use stage decoration in Jfx25 / JDK-8356115
• Consider AtlantaFx, and review OwlPlug dependency to Jmetro and controlsfx.
• Clarify UI Elements (View, Fragments, Component, ...) and package name (ui, component, controller)
• Consider custom theme support and like / dark color scheme.
