Several kontainer fuel switcher fixes

[Wyzard256]

Several fixes to the kontainers' FSfuelSwitch configs:

• Reduced the tanks' LqdHydrogen capacity to reflect the same tank volume as other resources. (It had been 4 times too big.) This makes USI kontainer LH2 tanks more consistent with CryoTanks capacities.
• Fixed some incorrect tankCost values. (Mostly small discrepancies, but rock tanks were much too expensive.)
• Fixed one tank that held 10 times as much argon as it's supposed to. (Seems to have been a typo.)
• Fixed tanks configured for LFO to be empty by default instead of full. (Seems to have been intended all along, but didn't work because the initialResourceAmounts entry said "0" instead of "0,0".)
• Fixed the quad-round tank being only 25% full of xenon/argon by default. (The other spherical tanks default to 100% full; looks like a copy/paste mistake on this one.)

There are two changes that I haven't made, but I think might be appropriate:

• Some of the kontainer tanks (at least the cylindrical liquid ones, maybe others) have 25% more capacity than similarly-sized stock tanks. I don't know if that's intentional, but if not, they should probably be reduced.
• ArgonGas capacity is significantly less than similar-sized NearFuture tanks, which can be explained as the USI tanks storing the gas at a lower pressure. It may be a good idea to increase the pressure/capacity to match the NearFuture argon tanks.

I'm willing to make either or both of those changes — let me know.

I've added the ArgonGas pressure change, after getting the OK for it in a forum post.
