VR Alfama modifications

[RoboDoig]

This is an issue to track the to-do list of modifications related to the VR Alfama project.

• All control should be done just with right controller
• Transparency on UI menu during point to origin
• UI menus should be larger, but don't fill whole screen - still need some peripheral vision
• Larger pointer (or user settable pointer size)
• Add support for setting the environment type (optimistic vs. adverse) on each session
• Update the pluma-vr package with modified components to facilitate git transfer
• Logging of px position when point to map
• Hide pointer cursor on map when not in use
• Potentially need a world position to px position for debugging purposes (for map), can test with a mode where you spawn on map point position
• Conversion of px position to world space automatically based on orthographic view and px position
• Support for multiple languages
• At the end of a trial show trial reset message
• UI should draw over other gameobjects #90
• Unity to GPS conversion #85
