Add support for more fluids in GT cells

[D-Cysteine]

This PR adds support for the rest of the fluids mentioned in this comment:

• [Quest] Pulverize the Planet #212 (Tier 4 EV) requirements bug GT-New-Horizons-Modpack#8748 (comment)

I had to refactor the metaitem 98 code a bit to get everything to work. I also added ore dictionary support for the Railcraft steam cell, so that we automatically get recipe support for it without needing to manually add recipes.

I also fixed the indenting in a large section of GT_Loader_Item_Block_And_Fluid.

Here's the complete list of added fluids:

• Drilling fluid (GT)
• Squid ink (GT; note that this one is 144L rather than 1000L, as that's what you get from one ink sac)
• Unknown nutrient agar (NH core mod)
• Seaweed broth (NH core mod)
• Super light radox (NH core mod)
• Enzyme solution (BW)
• E. coli fluid (BW)
• Penicillin (BW)
• Fluorescent DNA (BW)
• Combustion Promoter (Good Generator)
• Bacteria (Gendustry)
• Liquid DNA (Gendustry)
• Polymerase (Genetics)
