Handle shared objectives inversely in scoreboard (RFC)

[Pablete1234]

This is a discussion aimed at cores and destroyables after #995, in PGM up until now those objectives have always appeared under the team that has to attach such objective, so the scheme (red) 0% (meaning: uncompleted), and (green) 100% (meaning: completed) makes sense. However, when the objectives stop being displayed under a specific team, and are shared, this scheme may not make as much sense, and showing them from the perspective of the defender as (green) 0% (meaning: still standing, or still defended), and (red) 100% (meaning: destroyed, no longer standing). The green would be accompanied by a tick, and red with an X in case of non-obs and percentage not being shown.

This is open for discussion, should this be implemented? Does it make sense to change such a fundamental PGM thing or should we stick to what we have?

Referencing a couple discussions had over the past bit since this issue was made, the general conclusion seems to be that shared DTC/M objectives should appear as described here, while keeping non-shared DTC/M objectives as they currently appear and have appeared for years.
