[Mne_analysis] magflat and gradflat in mne_process_raw

[Matti Hamalainen]

There is no way to specify the "flat" limits on the command line of mne_process_raw, unfortunately. 

However, in the Averaging preferences dialog (Adjust menu) of mne_browse_raw there are "no signal" limits  (flat parameters) which affect the interactive computation of the projection operators.

I wanted to know of gradflat/magflat/eegflat parameters can be included in the mne_process_raw command. (I don't think this option is there in the mne_browse_raw gui structure.)
