Explosion tags on mech skills are useless

[Kodama.6453]

I know it is most likely a leftover from the time we had a trait that made the mech inhabit the explosives traits, but it is confusing for new players that so many mech commands have the explosion tag yet none of them interact with the explosives trait line in any way.

Rocket punch, explosive knuckles, core reactor shot and jade mortar all kept their explosives tag, yet it does absolutely nothing. Please either remove the tag or make them actually work with explosive traits, having the tag on them when it doesn't work makes no sense.

As a side note: please also fix rocket turret to trigger all explosion traits. Right now it just works with steel packed powder, but doesn't with short fuse, explosive temper and big boomer.
