Add ytick channel labels in vis_artifacts

[arnodelorme]

Transfered from Bugzilla.

Hopefully I am not overstepping, but I added some code to vis_artifacts in clean_rawdata0.32 after line 189:

channel_y = (ylr(2):(ylr(1)-ylr(2))/(size(new.data,1)-1):ylr(1))';

I added the code:

% add channel locations set( hAxis, 'ytick', flipud(channel_y)); set( hAxis, 'yticklabel', fliplr({old.chanlocs.labels}));

It changes the ytick values and labels to the channel labels in line with the data, so that you can see what clean_rawdata has done in terms of channel removal more clearly.

Note that the function should double check if the channel labels are available.

Accepted the change.
