- fixed bug that had a massive impact on prediction accuracy : the dry mass of the vessel was used instead of the total mass
- fixed bugs with the orbit patches (YZ are swapped by KSP, however it seems that doesn't change anything as it was canceling itself out)
- updating vessel info (mean drag and total mass) each frame (should fix issues with mods that modify drag over time, and of course correctly update predictions when fuel is consumed)
- added debug info during automated tests (display of estimated velocity and force corresponding to the actual vessel altitude)
improved automated tests (now copying logs after each test)
