[FieldTrip] EEG sensor position layout again

[Johanna Zumer]

Hi Hweeling,

I just checked on my computer, and it helped to restart matlab and try
again.  Maybe there is something strange if ft_defaults is called (again)
during an already open session with previous calls to FT functions?

Best,
Johanna
