remove useless IndustrialMineral.getPhaseProperties()
remove Fuel class; if we have one, it won't be in Geologica
use Strength ordinal for harvest level configs; makes the ordering of
the options more intuitive (must be lexicographical)
just some fluid block sketching in prep for petroleum support
add missing GeoMaterial convenience constructors; was causing
pure minerals to register as generic mixtures
forgot to initialize a List
Liquids are now very light blue by default (much better than null!)
add Solid convenience constructor
make implementation of Formula private; add support for storing a
SMILES string (may be useful for organic compounds)
add missing FlowingBlock
add some sketchy petroleum definitions
textures for petroleum stuff
