v4.2.45

This update makes FabMo much better at recovering when it
loses contact with the tool's motion controller, often
without turning the tool off and on.

New:

• FabMo now tries to recover a lost motion controller by itself,
  resetting the USB connection if needed.
• FabMo reconnects automatically the moment the controller comes
  back, such as after reseating a cable.

Improved:

• If recovery fails, the dashboard now stays available and shows
  Reconnect, instead of restarting the software.
• Clearer on-screen messages explain when FabMo is reconnecting
  or attempting USB recovery.

Fixed:

• FabMo no longer gets stuck at startup when the motion
  controller stops responding.
• A garbled message from the motion controller no longer
  crashes FabMo.
