People App redesign

[Armored-Dragon]

This is a redesign of the People app that streamlines everything from usability to development.

TODO:

• [ ] Housekeeping
• [ ] Test in VR
• [ ] Color adjustments (Some colors may be hard to see in some conditions I have not tested in yet)
• [ ] Make adjusting persona options more obvious
• [ ] Better contacts page (It's a bit rough to understand)
• [ ] Documentation
• [ ] User selection distance based fallback (Halo turns into a dynamically sized indicator so that the position can always be seen)

Current user page	Selected User page	Contacts page
Edit persona page	User selected halo	User selected halo occluded

The user selection halo is a mega cool idea. How about falling back to something else, or scaling it together with a written distance, to make it easier to see people who are really far away?

The intention of this app will also be to move the other two existing PAL interfaces to /script-archive. That will be a separate pull request. I would also take the opportunity to clean/remove some global assets, most notably the app icon, and keep them in their respective folder.
