Fixes for screen HUD object icons.

fixes icon on the HUD screen not appearing if the objects were added by another player with the strip panel.

This should also swap under the carpet (kinda ugh because the problem is still there and it might affect some other things) the problems with the roundstart missing player's icons on high populated servers.

This should be the first step to reduce the amount of calls on the different icon update procs, but for the moment I'm focusing on more CPU expensive procs.
