NeroTech 0.2.1-beta.1

Gases move through pipes, one oxygen shared with Nerospace, and the gas textures load. Pair it with
Nerospace 1.1.1, whose Universal Pipe now connects to NeroTech's gas machines.

Fixed

Gases move through gas pipes, and the Electrolyzer drains (#9)

• One oxygen, shared with Nerospace. NeroTech's oxygen is now nerospace:oxygen, the same gas
  as the Nerospace Oxygen Generator and life support. The old separate nerotech:oxygen gas meant
  the Chemical Processor refused Oxygen Generator oxygen even when a pipe delivered it. NeroTech
  still does not depend on Nerospace: the id is only a name.
• Legacy oxygen migrates automatically. Tanks saved with nerotech:oxygen load as
  nerospace:oxygen. NeroTech machines accept nerotech:oxygen from any source, such as a Core Gas
  Tank filled by an older build, and store it as the shared gas. A turbineGasBurn entry for the
  old id counts for the new one. The transport fluid keeps its registry id nerotech:oxygen, so
  other mods' pipes and tanks keep their contents. It now stands for nerospace:oxygen.
• Gas pipes carry NeroTech gases. With a pipe on Core's nerolandcore:gas capability (such as
  the Nerospace Universal Pipe from Nerospace 1.1.1), the Electrolyzer's products
  flow out and into the Chemical Processor, the Gas Turbine or a Core Gas Tank. Those machines
  accept gas on every face by default and pull from an adjacent pipe or tank on their own.
• The Electrolyzer's gas faces are output-only. An I/O gas face used to take gas back, so a pipe
  that both pulls and pushes returned every millibucket and the product tanks never emptied. The
  machine then stopped with full tanks. On Core's gas capability, I/O now means output for the
  Electrolyzer, and an input face takes nothing.

Crash reporting

• Crash reports no longer include vanilla's "Invalid block entity" message. Minecraft logs it when a
  chunk's saved NeroTech machine data no longer matches the block there, for example after another mod
  remapped blocks. Vanilla discards the stale data and the world keeps working. Exceptions thrown inside
  another mod's own code are no longer reported either.
• Hydrogen and oxygen fluid textures render. The sprites lived in textures/fluid/, listed by
  an assets/nerotech/atlases/blocks.json that Minecraft never reads (atlas definitions are read
  from the minecraft namespace only). The sprites were never stitched, so both gas fluids drew
  the missing texture in tank and pipe GUIs and JEI. They now live in textures/block/, which the
  block atlas always includes.
