Planar Gradiend for bti148

[Robert Oostenveld]

Hi Julian,

A quick glance at the megrealign code shows that there is some hard-
coded dependency on the ctf gradiometer definition, where only the
bottom coils should be used. However, that should not be a limitation
for bti148. Apparently Jan-Mathijs already has got it to work on
bti248. I have made two changes (one for checkdata, the other for
ensuring that grad.unit is known). Please try with attached version,
this will be in the fieldtrip release on the ftp server tomorro evening.

best regards,
Robert
