Have players only control & see their own units

[stefanhendriks]

Depends on:

• Render wheeled units #25 rendering units
• Ability to uncover shroud #37 revealing shroud

Acceptance criteria:

• A team has a base color
• The base color is visible on units/structures
• A team has their own unshrouded map data (see Ability to uncover shroud #37)
• Renders units with team color (depends on Render wheeled units #25)
• Renders structures with team color

Note: players are not 'humans' but more like 'sides' (teams).
