Fix depth charges not applying the ProjectilesToDeflect blueprint field

[Garanas]

Description of the proposed changes

Fix an issue where the blueprint field ProjectilesToDeflect of a depth charge was ignored. It would always default to the value 3.

Testing done on the proposed changes

In the following test case I increased the redirect count of the depth charge of the UEF Destroyer to 10.

"Depth charge" is confusing with the depth charge weapon. I think we should use "Anti-Torpedo Flare" because that makes sense when you know about Aeon tactical missile flares, and the name is already used by the Mermaid, Brick, Megalith, and Barracuda. UEF's display name is "Smart Charge AntiTorpedo" and Salem is an outlier with "Anti Torpedo Solution".

I tested it out with UEF destroyers and when I set the ProjectilesToDeflect to eg. 10 then the"depth charges" redirect nothing.
Maybe some of my other changes mess this up? Idk, will retest
Edit: Idk if it was something to do with the set up or my other changes but it works as intended when I cleaned up everything.

You have to respawn the units for the changes to take effect since this mechanic uses the weapon's blueprint, and blueprints are cached on instantiation (self.Blueprint), so you have to respawn the unit and its weapon for it to update.
You may also find useful the hotkey "toggle collision debug information" (equal to dbg c console command) to see how the projectiles hits the flare's hitbox, and increasing the projectile lifetime in the antitorp weapon's blueprint so that it can catch more torpedoes.

I agree, but we should process that in a separate pull request. It's also a little tricky because if we change the names (of the Lua classes) then we'll also break mod compatibility.
