Explosives - Add "ace_explosives_setup" CBA Event

[ThatArcanist]

When merged this pull request will:

• Add an event to the "fnc_setupExplosive" for when an explosive is successfully placed down.

Currently, the "ace_explosives_place" event only triggers when a "trigger" is added to the explosive. This adds an event that passes in the placed explosive's vehicle, the mag class and the unit that placed the explosive.

Personally, the current event should be renamed and this one should be named "place" however, to avoid fallout with other mods that depend on this one, I've simply created a new one to keep the two separate and not cause other mods to need to be updated.

I have added back the IMPORTANT section of the PR template that was removed. Please complete the 3 items in that section.

@BrettMayson The event "ace_explosives_place" is undocumented, would you prefer I left this out of documentation or created a section for the two events (ace_explosives_place and ace_explosives_setup) in the explosives framework documentation

[BrettMayson]

I would document ace_explosives_place if it is missing

Title of this PR should be something like Explosives - Add {changes}

Descriptions were fine, just event naming that was backwards.
Disregard.

[ThatArcanist]

@LinkIsGrim Could you be more specific? Both the descriptions (You didn't mention it, but I also noticed it was wrong) and naming was fixed, if there's another issue, I can't see i t
