Reduce prices of explosives for nukies

[Blackern5000]

About the PR

Nukies now have to pay half as much for the following explosives compared to traitors

• EMP grenades, 1tc each
• C4, 1tc each
• C4 bundle, 6tc each
• Explosive grenade, 2tc each
• Explosive pen, 2tc each

This specifically does not apply to minibombs, suppermatter grenades, whitehole grenades, shrapnel grenades, or incendiary grenades.

The grenadier rig now contains the following items and costs 10 tc

• Explosive grenade x6
• Shrapnel grenade x2
• Incendiary grenade x2

Why / Balance

• C4: Since AI was added, nukies haven't really had an option for getting through bolted doors aside from subverting or entirely removing the AI. (they could technically hack through but good luck doing that while under laser fire) This change allows them to either stock up on C4 at their base with 6tc bundles, or buy it in the field as needed to save bag space with individual 1tc purchases.

• Explosive grenades and Explosive pens I NEVER see these used in any meaningful capacity during nukies, despite being potentially very helpful, they just are not worth the cost. Consumables are generally pretty iffy with nukies compared to traitors, since it's a case of taking on the ENTIRE CREW vs killing one or two guys to maybe steal something in the process. Even if the trade of 4tc to kill the hos is worthwhile, it's not hard for them to be evasive. The explosive grenade has its uses for clearing rooms or destroying medbay (byebye chems!!) meanwhile the pen has its uses for better securing a kill on individuals. But until now they've both been outclassed by the china lake due to it being an instant explosion upon hit and generally providing more explosives for your tc. 4 very good bombs and 8 good bombs for 25tc vs 6 okay bombs for 4tc each (24 total) is just not comparable. At least now you get 12 okay bombs for 24 tc.

• Grenadier rig With EMP grenades and explosive grenades becoming significantly cheaper in this pr, and minibombs being so so punishing to friendly fire with while not being all that good at killing crew means the entire bundle wouldn't be worthwhile really ever. So I felt turning it into a sort of c4 bundle for murder bombs rather than utility bombs would serve it well. Shrapnel and Incendiary grenades are still left expensive for nukies so I felt including them would make it more worthwhile to buy. I also made it slightly larger internally than other chest rigs (10x2 instead of 8x2) to hold a couple more bombs, probably not that important balance-wise since most of your storage is in your bag anyway, but could be big for someone running a backpack water tank.
