Version 2.6.0.0

• Full support for Rimworld 1.2, on a shared codebase with 1.1
  • Shunted rimworld 1.0 assemblies into a 1.0 folder too.
• 4-10x faster load speed on "running post-finalize callbacks" (stage 9) due to me making a stupid mistake ages ago.
  • This comes to both rimworld 1.1 and 1.2 (because they share a codebase)
  • Sorry for making the error in the first place!
• I also now include the assemblies on github - but this zip doesn't contain the source so is smaller (by about 40kb)
