V3.2

These are my changes intended for v3.2.

Main features
* better handling of Landed (fewer explosions)
* autodetect kethane for control of debug
* smaller smelter and auger (just rescales)
* new recycler (range based is gone, now uses a trigger collider). Two sizes of recycling bin included. Dumpster diving may be dangerous.
* non-pumpable/no-flow resources use rocket parts when building and are not reclaimable when recycling.
