bug using planarcombine and with planar 4d/bti data

There seems to be a small bug with using using planarcombine with 4D/BTI
data after using megplanar. It reports the gradiometer type to be
'bti248' instead of 'bti248_planar' which it should be. The problem is
with senstype function, where it puills the definitions from .hdr.grad
substructure first instead of .grad substrutre (line 109) which is the
one that  has the planar-transofrmed definitions.

I just swapped the order inwhich the function looks for gradiometer
definitions so that it looks in .grad first instead of .hdr.grad. It now
correctly reports the gadiometer type as 'bti248_planar'.

Many thanks
