[boost] [mpl] Iterator categories for sequence views

I'm not sure about this, but I think the iterator categories for 
joint_view, transform_view and filter_view are wrong. At the moment they 
are set to the category of their base iterator, but I think that they 
should be set to forward_iterator_tag (or maybe input_iterator_tag?) 
because they don't implement prior, advance or distance.

I think this is the reason that the attached file fails to compile.

Of course, this might not be the case in the new version?
