Close #5101

Allows mission/addon makers to block detonations in the explosive system.
See example in addDetonateHandler.sqf

Having the examples in the wiki would be splendid 😄

I noticed there is no way to remove a DetonateHandler, because it is using a simple array for storage. I don't know if we want to just communicate that in the wiki, that you cannot remove a DetonateHandler and must provide your own way of disabling it, if it's not required.

During testing it seems that cellphone triggers don't trigger the DetonateHandlers. Investigating further.

Okay, I found what the issue is. Timer based explosives and Cellphone explosives use -1 as range. The example code has a check for range initially and allows the explosion if range is < 0.

So I guess maybe just change the example code to have the cellphone check before the initial range check.

Looks good to me
