0.192.26 - Fission Heat

This is a bugfix release, patching up the recently found bugs. Changelog:

• Fixed a race condition in geologist code that could cause a game to crash if lot of minerals were identified in quick succession and some of them left the detailed simulation area promptly.
  
• Fine-tuned AI pathfinding behaviour to make mining ships more careful when navigating the obstacles in rings.
  
• Fixed a race condition in ship dealer that could cause game to crash if you entered and exited dealer multiple times in quick succession.
  
• Fixed a bug in adaptive autopilot code that caused it to be very wasteful when flying with variable-thrust NTR RCS.
