PR #5967 only made planes not lose their selection when they strayed
outside the map border. This PR makes it possible to select them when
they already are outside the map. It also ensures that the selection
decorations are drawn. Rank designations, however, will disappear when
a unit leaves the map.
Fixes#5651 for real, then.
-Palette for decorations can now be defined under SelectionDecorations trait.
-Adds pip types Ammo and AmmoEmpty.
-LimitedAmmo PipTypes are now customizable.
-Adds art, sequences and rules entries for TS mod decorations that were missing/using a wrong palette.
-Adds PrimaryBuilding trait to TS weapon factories and helipads.
- Each player has their own shroud and their visibility does not extend outside of the shroud.
- Units and buildings can no longer target other units outside of their visibility. Buildings can still be targetted if they have been explored.
- GPS will provide visibility in the fog-of-war.
- Spies that infiltrate radar domes will gain their victim's exploration and reset it on all clients (if the victim does not have GPS)
