Validate Scenario feature.

[tomsons26]

This would validate a lot of stuff in the scenario.
Triggers, teams, placements, various mistakes that can go unseen by the map maker and output it to a log.
This feature should be available in release builds.

For example say you got a trigger that needs a attachment, but you haven't attached anything
so the trigger is broken, this feature would report this,
The internal editor just lets it slide if you don't attach anything so this can result in people making broken triggers.

Another example where you have a trigger that makes a reinforcement team, and the reinforcement team has the same trigger attached to it.
This would result in a infinite loop making the team over and over again.
(a very common issue with user made scenarios cause there's no information on how this worked)
