at some point the gradiometer structure and the volume conductor model are processed by prepare_headmodel (which is a wrapper around ft_prepare_vol_sens), where only the MEG sensor coils are kept. Apart from this being not entirely correct (e.g. 3d order gradient balancing) it causes a crash when later on in the function some plotting is done (due to a crash in channelposition)

ft_megrealign calls deprecated ft_headmodelplot -> this is now changed. the issue with the channelposition bug seems not to exist anymore. going through the code with respect to the balancing issue, it seems to me that the function deals with it in a correct way. created testscript in revision 4740
