add support for industrial fluid buckets; add custom gas behavior;
support coloring of liquid ceiling drips; materials (and fluids) have an
opaque/transparent property; moved fluid textures from geologica to chemica
tweaks to petroleum world gen
remove the BC-inspired disallowing of all liquid displacement
start working on helpers for temperature-dependent flammability and
instability; not sure if these will ever be used
add missing imports
rename molten attribute to superHeated
add ChemicalConditionProperties that stores the thermodynamic
properties for a specific condition
add helpers for getting conditions at specific world
coordinate (biome/height dependent); not sure if this will ever be used
support fluid flammability (fire spreading, lava ignition, flowing
into torches/fire); lava ignition does not yet work for liquids
now building against 1.7.10 (Forge 1180)
