UI: Circlemenu: Make circle-images colour-agnostic, implem team-based colours
UI Fix: hide pause-menu when changing a team from there
UI: Large amount of HUD tweaks

Shared HUD
 - Move map-location to above gameplay stats (fps, time, etc)
 - reduce reticle opacity

Momentum bars
 - Move slightly lower
 - Remove background colouring of icons + recolour them
 - Improve human mom-bar subtlety, so it blends with the rest of the human HUD better
