add / reverse engineer seeyou thermal detector

[GliderGeek]

does anyone have any clue on which basis seeyou makes this distinction?

ideas for achieving this (thanks to @roeles):

• manually crafting an IGC file and run that trough SeeYou. This can be done with aerofiles.
  hopefully it doesnt care about the security entry

Perhaps @Turbo87 has a clue.

no idea about seeyou, sorry. XCSoar does it by calculating the rotational speed and if that is above a certain threshold for X seconds it switches to circling mode.
