Explosives - Add Tripwire Flare Air Variant

[Mike-MF]

When merged this pull request will:

• Adds a new tripflare item that fires into the sky instead of on the ground.
• Adds setting for the tripflare colour (default is Red, which i think is what the original one did. Not sure, colourblind.)
• Kept the old tripflare class for BWC, just no longer used here.

IMPORTANT

I'd prefer to just add a 2nd magazine instead of a setting

That'd mean duplicated code as the effect only passes the position, so no way of detecting what kind of flare would have been activated. The setting is just the simpler solution here.

By having a setting and changing it to air mode, all mission that have been previous made with ground flares now have air flares. I don't think that's desirable
As a mission maker I might like to be able to give players a mix of ground and air flares, or places a mix in a defended area in the editor.

I don't see a lot of duplicate code being added to implement that. A couple of additions to CfgCloudlets.hpp and something like TripflareAirEffect.sqf that adds a little height to the initial Z position when calling the spawnFlare function.

I'm not a huge fan of having the color be a setting. Is there no way we can have it passed as an argument or set as a config entry?
