TaskGarrison and taskCamp to trigger on internal eventhandlers

[nk3nny]

Explore enhancement:
TaskCamp and taskGarrison should trigger on internal eventhandlers instead of the "FIRED", "HIT" and "ENEMYNEAR" ones. It will allow for much more reliable conditions if we use our own eventhanders-- and it will escape problems because mission makers add their own.

It may also let clean-up be an easier thing.

I suspect this system can be linked to #115
For cleanliness I will close for now. Implementation will not occur before 2.6 in either case.

let it open when you have it assigned to 2.6.0

With the introduction of: https://community.bistudio.com/wiki/Arma_3:_Event_Handlers#Suppressed

BIS Suppressed eventHandler. That might be a better and faster approach to achieve the same. Suppressed EH also passes a bunch of other very interesting information too.. humm humm!

I think this should be closed.
