Introduced IconInfo

AttackableUnit

• Moved CharData down from ObjAiBase.
• Introduced IconInfo.
• Introduced override functions to OnSpawn and OnEnterVision in order to properly handle changes to minimap icons

GameObject

• Introduced TeamsWithVision, which returns all teams that have vision of that unit. This is used to assign all teams that had vision of that unit when it had it's icon updated, in order to prevent repetitive calls every time the unit went in and out of vision.

Events

• Fixed an issue where manually removing a triggered listener that has singleInstance = true would cause a crash or remove the wrong listener.

Spells

• Fixed spells with 1 MaxAmmo not getting casted due to CurrentAmmo being 0 after the first cast.

The introduction of IconInfo results in the Unit's icons now being properly updated to the clients when changed before the unit's spawn being notified or or when in the FoW to said clients.
