VR UI Components

[tparisi]

The Kickstarter stretch goal (see https://www.kickstarter.com/projects/dodocase/diy-virtual-reality-open-source-future). Identify and develop a simple set of UI components for layout, interaction, etc.

We can start with the current DODOcase VR store in landscape mode... a simple planetary system with app icons as cubic moons. Needs to be refactored from old Vizi code to full GLAM implementation.
